Was having huge issues with freezing and crashing to reboot, then I uninstalled everything (AC, CM, Pure and CSP) and did a fresh install (one at a time) of AC (plus did the Steam validation check, all good), then CM, then CSP/Pure (had to bump up to V2.0 on CSP for Pure -- version above the recommended 1.79).
Also, reverted my GPU back to a six month old driver that various folks in forums had said was more stable for gaming in general and AC specifically.

Currently:
No crashes to reboot but still getting freezes (while racing or getting wrecked by AI) with the sim running in the background and then eventually goes to desktop with a CM pop-up and my AMD Error Report window also opens...

AMD says a driver failed to respond while CM says (copy & pasting the latest two reports for you)...


Error might have something to do with:

00007FF84ED9543C (KERNELBASE): (filename not available): RaiseException
00007FFF85232F90 (DWrite): (filename not available): DWriteCreateFactory

System Specs:

Ryzen 7 7700X CPU (not OC'd)
Asus Prime B-650 Plus Mobo
AMD Radeon RX 7900XT (not OC'd)
Gigabyte M34WQ - 3440x1440
Win11 64 bit
Running CM in Administrator Mode (also read somewhere that that is recommended)

Any help or insight greatly appreciated.
 
What’s happen if you start with AC directly without CM?
About to try that today... also worth noting:
I pulled the 7900XT card and reinstalled my old 3070Ti - DDU all the AMD & Nvidia drivers in safe mode before the swap. Installed latest Game Ready driver for the 3070.
AC worked good for about 10 minutes and then I started getting freezes, sim running in the background behind the frozen screen while my FFB wheel was still responding to input from AC before dumping me back to desktop via Task Manager.
MS Event Viewer and CM both gave me the same code...

"Display driver nvlddmkm stopped responding and has successfully recovered."
Very similar to the same error log when I had the AMD card installed except the driver was named "amxxxxxxx" something or rather.
 
*Edit*
The log for the AMD card would read-

"Display driver amdwddmg stopped responding and has successfully recovered."
From what I've gathered it's basically the same exact event as the Nvidia card but obviously for AMD.

Never had these issues before swapping cards, and perhaps interestingly, installing AC, CM, MODS and my Logitech G923 + G-Hub software (the issue is one, some of, or all these) as I just started sim racing four weeks ago, and bought all these items then, after 20 years off from the activity.

Another question, what's the best location to install CM? I read somewhere it shouldn't be in Program Folders... I've only ever installed it to my desktop -- could that be a problem?
 
If nobody can explain the logs then I would start over and delete all.
install AC. test ride OK then,
install CM test ride OK then,
install your mods test ride with mods OK then,
install CSP test ride OK then,
install pure test ride OK then etc etc
Until you find the cause
Do not know if it is the right order but only with small steps you get to the cause.

BTW long time ago I did install CM and at that time it did need some additional software, otherwise it did only showing errors.

Could it be your CM is referring to AC86.exe, just a guess.

What is AC86.exe? Is that a correct or incorrect extension for the actual executable? Not currently at my PC so I am unsure.
 
You have a 64 bit system ... so keep AC running 64bit with Content Manager.
It is 64 bit at the start except if you checked the "Use 32-bit version" in Settings/Content manager/Drive on the left in the very first line there.
( in the case of 64 bit that's the acs.exe which is used and not the acs86.exe )

Content Manager is a portable software, you can install it anywhere you want.
Personally, rather avoid a Program or Program Files C: folder .... rather choose a place even on another disk than C: and I also avoid to install it in AC program itself.
Everything it saved goes into AC Documents files ( for AC settings ) or in your Appdata ( for CM settings)

If you have problem .... maybe try to avoid too heavy settings for CSP and Pure.
That's the first option to try: for example unactivate Extra FX in CSP settings ... that's a rather heavy feature.
The problem seems to happen no matter which GPU you're using .... but the problem might be somewhere else.

Thank you, I'll give it a try... also, I have unpacked CM to my Desktop when I first opened/installed it, is that okay?
 
Ok let’s go back to the basics, as we still do not know what to search for, my suggestions. Is it your:
hardware?
OS?
AC game includes the pure, CM etc?

1). Hardware, do a stress test, first.
Download, a free CPU, GPU, SSD and a memory test software, Google and try them. Tip, use HWmonitor, CPUz and GPUz to check if nothing is going out of limits.

2). OS, is everything running fine while searching for stress software then I guess it’s ok.

3). AC, doing the steps as I already did explain, for installing them, use the YT video from @PeterBoese.
Tip, for doing test runs use Kunos only stuff and use the performance app from the right vertical interface to watch what’s happen.

Latest weirdness, even though I uninstalled AC and CM, and then reinstalled AC only via Steam and verified files, when I open AC I am seeing a CSP version at the bottom of loading screens.
Obviously I missed something during the uninstall - can I get some assistance on where to look for all the files for both CSP and CM as I quite obviously missed some when uninstalling.

Also, when creating a practice session or race I am seeing SOL under Weather which leads me to believe I haven't properly purged Pure too.

This is frustrating. I know I am no PC expert by any means but I'm not a rank beginner either... what the hell did I do?!

Can someone outline a thorough post on completely uninstalling everything so I can, yet again, do a vanilla install of AC?

Thank you for all the help.

delete AC from steam. Also delete Assetto Corsa from your documents folder. Delete content manager stuff from here:
C:\Users\ username\AppData\Local\Temp
and where ever you put the content manager .exe may as well delete that too. Maybe run CClean to get rid of stuff in the registry. Then reboot the computer, install AC from steam and run the game make sure everything works. Then you can start from scratch and mod the crap out of it.

Latest update... uninstalled everything and reinstalled only AC... now I can race for a few minutes and my screen freezes with sim running in background, eventually either kicks me to selection menu within AC or to desktop.
When I check event viewer I am seeing "nvlddmkm failed to run but recovered" after every freeze/crash... I've repeatedly used DDU in Safe Mode disconnected from the Net to reinstall the newest (to other recommended) Nvidia drivers all to no avail.
Getting closer to doing an entire reinstall of Win 11 even though I've done checkhealth/scanhealth/repairhealth numerous times all with zero issues found... repeated virus programs run, all come back clean.
Suggestions?
AC is the only thing this happens with.

Does AC crash when using the built in benchmark or a replay? Are you aware of Process Monitor - it records all the process/thread activity that takes place on your PC in real time, so it can help pinpoint what instructions are occurring @ the time of the freeze/game crash.
