• crashes when launched from Steam (which launches some launcher, hitting play there causes crash...)
• crashes on exit (when launched directly from EXE)

@WSSDude game started from .exe file crashes, even when there are no mods.

I know, found out shortly after I posted the comment about launcher crashing.
Debugger has to be attached for some reason for it to not crash.

I know, found out shortly after I posted the comment about launcher crashing. Debugger has to be attached for some reason for it to not crash.

That's probably because there's small code-snippet in src/dllmain.cpp:23 which forces the game to wait for a debugger to be attached:

while (!IsDebuggerPresent())
    Sleep(1000);

That code-snippet is always executed as soon as CET is loaded by an application via the ASI-loader, so take a look at the launcher-executable using something like System Informer if it indeed loaded CET

Edit: Maybe a few checks should be added that CET is indeed running in the actual Cyberpunk-Executable
