Playing in VR with Quest 2 on Unreal 5.1.1 with Quest Link crashes in RuntimeIPCSystem thread
I'm working on an Unreal 5.1 project using MetaXR and OpenXR plugins. Lately I've been unable to play in VR mode on my Quest 2 in Unreal due to this crash. The crashing thread is RuntimeIPCSystem, and here is the exception message:
Exception 0xc0000005 encountered at address 0x1ef7fa73ef0: User-mode data execution prevention (DEP) violation at location 0x1ef7fa73ef0
Another interesting note is when this crash happens, the Oculus App closes and reopens and Quest Link won't work until I unplug-replug the cable to my Quest 2.
Here are some details about my circumstances:
- Nobody else on my team has experienced this issue, and I have tried a fresh pull on the project with the same result. This leads me to believe it's a local issue on my machine.
- I've tried using DebugGame and Development editor build configurations with the same result
- I've uninstalled and reinstalled the Oculus App twice
- I've done a Windows restore, where I reinstalled Windows while keeping my apps and user data intact.
- Running in VR mode in Unreal editor without Quest Link active will NOT crash
I'm suspicious of the Oculus App and Quest Link, but reinstalling the Oculus App hasn't helped. Is there anything I can do to completely wipe my Oculus App data in hope of resetting whatever is broken?

I am experimenting crashes on a project that was working before, even on build. It is an unreal VR 5.1.1 project running on Quest Pro and using MetaXr plugin. It crashes on launch of the project and like you the Oculus App closes and reopens. It must be an update of something become it was working before. it is stressful become I can't even open the project.

Wanted to provide an update - A full Windows reinstall (keeping user data) fixed the issue.

I really think it has been fixed by Meta because for me it was working again without doing anything except Oculus update.
