GTR233
Since v14.x the modded part HQ Cars&Tracks are totally independent from base game files which are stock (not modified by HQ Anniversary Patch). Base game is only skinned by new images so it is quite impossible that the crash is due to HQ Anniversary Patch : I think you've installe either a bad mod or you have a conflict between 2 mods. I don't know the mods you are speaking about : send them to me via your google drive or tell me which mod exactly it is and I will investigate :)
Please run GTR2_DEBUG.BAT then after crash, go to UserData\log\ and open trace.txt with notepad : scroll down to last lines and the reason why GTR2 crashed should be written.

I always recommend a clean fresh install for any new update, and at first launch run GTR2_DEBUT.BAT to clean junk files then you can use GTR.EXE :)
It's a short memory issue, the problem doesn't come from your PC but the way a 14 years old 32bits GTR2.EXE works. Many people on many forums (steam first) suggest to install the old nocd : this is the worst idea because it is limited to 1.8gb RAM, so if you load recent mods/tracks converted from AC/ACC/RF2/F1 20xx codies then your allocated 1.8gb of RAM are full and Crash-To-Desktop without signal in trace.txt file.
Both NOCD1/NOCD2 in HQ Ann. Patch are 4gb patched so you've got an extra 2.2gb of RAM allocated which means you can load a bit more Ai cars without CTD, but at some point you will reach 4gb RAM and CTD too. The new games such as AC/ACC/RF2 are 64bits and can use all your pc RAM available so this is a problem when you convert material to older games as GTR2.
By example, with old nocd of 1,8gb ram I can run around 20 high polygons AC cars, and with 4gb patched NOCD1/2 from HQ Ann. Patch I can load 35 AC cars...but I have CTD at 36 cars grid. Of course it will be even less cars if I run them on heavy tracks >100mb.
So my advice is to reduce AI opponents when you run heavy mods/tracks to not exceed 4gb RAM allocated.
