From my side I can say that it is neither a virus nor malware or anything else. I have written the code completely. This is probably the reason for the problems as the code is simply not written professionally enough and therefore looks suspicious.
Unfortunately I don't have the knowledge to fix the whole thing.
But of course I can understand if you don't want to take any risks.
Alternatively, you can of course use the original method to install the mod.
I'm sorry
