Hi,
I tried to convert my VR project from 4.21 to 4.22 but I’m experiencing a crash on the engine.
I have pinpointed the issue coming from the motion controller. The project runs fine until I touch the trigger button on the controller, crashing the engine and giving me an error of EXCEPTION_ACCESS_VIOLATION
Log of the crash:

I’m using Oculus Rift and this happens when playing from the editor or standalone.
Any ideas where the error is coming from?
