Just GTAV ?
Have you tested on any other games whereby same thing happening?
Rebar enabled? If so try disabling it and see if problem persists.
PX1 running in the background? Try disabling it
 
When you updated vbios did you update both vbios chips or just one? If just one, try switching to other vbios and see if the probelm continues.....
 
You're basically "detective mode" and trying to isolate the problem.

It does happen time to time for Diablo 2 Resurrected but not sure if it's the game or my pc as D2R is notorious for random crashes but GTAV Cyberpunk 2077 or any other game I never had this issue.  My ram is a 3200mhz kit so those are running at speed.  CPU temps really don't go over anything over 75c-80c at a spike and gpu is around 70-80, so I'm not sure what happen all of a sudden.  I did try to set priority on GTAV last night on task manager and i did end up playing for more than 10 mins before it I went to sleep, and didn't crash.  so i'm not sure what it is..

Try lowering the core and mem clock on your gpu to max negative values via msi afterburner. See if that helps. If it doesn’t try the other vbios on your card since it sounds like you only updated one of the two vbios chips that comes with your card. The vbios selector switch can be located to the left of the power inputs on the card.

If those two things do nothing try checking your system memory with memtest86. If no errors show on the memtest, and the issue is still occurring try using windows system restore to restore your pc to a day when the issue wasn’t happening.

had the same issue when I jump into RTX cards.
10-15 min of play, GTA V or Cyberpunk, and crash to desktop, no error, no event log.
 
Did a DDU, win10 reinstall, crystal diskcheck, memtest, cinebench, passmark ; nothing was crashing.
 
- 1st thing I check was the memory. Using spare ram, and even lower clock, increase voltage, lower voltage : same.
- 2nd , put my CPU to stock value : this did the trick, but I can't leave stock values, its a i7 k series...
I was about to ask my friends to test my GPU before RMA.
 
- By testing and error, I found out my core # 4 didn't win the silicon lottery ! Damn I had to dig far to understand what was wrong with my CPU,only when I un-sync my cores its coming stable, and tried random values.  So sync cpu 45-45-45-45 = crash. 46-45-45-42 = stable,
 
Could be a tons of stuff. A friend of I was his cheap PSU, not because it wont give power , but won't stand outlet power variation, he used a UPS and fixed.
An other friends, was his external hard drive dying, and when win10 tried to access it while gaming, the game just crash.
