Oculus Link fails to start. Windows 10 kills OVRServer_x64.exe, "an overrun of a stack-based buffer"

TokyoPiglet

I have been unable to start Oculus Link with PC Oculus App Version 31.0.0.47.507, and Quest 2 at version 30.1.0.61.350.300158191, Runtime Version 30.1.0.60.351.300158234, OS Version user-17007100222900000. 

 

When I enable Oculus Link from my Quest 2, the PC Oculus App restarts itself. Windows 10 saved a CrashDump of OVRServer_x64.exe so I used WinDbg to analyze it:

Apparently, the OVRServer process is mishandling its stack. Am I the only one experiencing this problem? Can the Oculus team please examine this problem?

My Oculus App (30.0.0.36.502) does not restart but Link will try to connect for a few seconds and dump me back into the Quest Home. I have the same Quest 2 SW version and Runtime version as yours. Only started acting up yesterday. Was fine for the last 6 months of use.
