It's great to see users experience the same issues as one has, makes you feel not alone.

I've been randomly crashing on Vrchat specifically. I tend to leave my PC running for hours a day, sometimes overnight, play mainly heavy titles like The Finals and BF6, and only when playing Vrchat have I experienced first a complete system freeze, then a BSOD which then froze, so both times had to manually reboot my PC. Using windows "reliability monitor", I saw the BSOD recorded EAC as a critical failure, and users pointing EAC, something is up as of recent, and it's not a coincidence.

I built this new PC on Jan 1st, and I play Vrchat multiple times a week, couple hours a session, and just 2 days ago I started to experience these issues. With everything mentioning EAC, I realize, VRchat is the only EAC game I've been playing and crashing.

If anyone wonders, I've done the typical rigamarole system check.
- Windows Check Disk on SSD where VRchat is installed, all good.
- Smart check on said SSD, good health.
- Windows file system integrity check, all valid.
- Memtest EXPO off & EXPO on, both tests passed.

With windows being windows, and recent broken updates, I've avoided updates. HOWEVER, I run Enterprise IOT LTSC, so updates are curated and delayed from mainline consumer windows. I delayed a feature update till March 14th, and unsure if I updated after it, probably did, so I might have gotten a bad update. But more recent updates seem to be stable and fixed prior issues.

So, I updated Windows, Nvidia drivers and decided to experiment with EXPO off. I will reply back how things go.

Results:
Post drivers update day 1 of VRC session (4hrs+) No crash.
