Hi! So, after I've reinstalled my pc and installed GTA V, it keeps crashing while playing, absolutely randomly. Happens both in Online and Story mode.
ALWAYS crashes after around 15 minutes of gameplay.
The things I've tried so far:
Reinstalling Windows on my PC, 3 times..
Verifying the game's integrity in Steam (Game's completely fine according to Steam)
Redownloading and installing the whole game
Reinstalling DirectX, Social Club, vcredist
Renaming rockstar games folder in documents to rockstar games-old, and let it create a new one
Reinstalling NVIDIA drivers
DDU NVIDIA drivers and install them again
DDU NVIDIA drivers and install older versions that worked fine with the game
Reconnect my GPU

But to no avail, none of these fixed my issue.
I'm pretty much miserable at this point.

No popup appears, that GTA V stopped responding. It just randomly quits the game, and then the "safe mode" popup from Social club appears.
I even stress tested my GPU with Kombustor for 40 minutes to see if there are any issues with my GPU. Everything just fine, no crashes, nothing.
No other games crash btw.
