Please and attach crash logs and dump files from your project directly after a crash, as well as your system information.
There is a known issue with LPV and translucent materials that will instantly crash editor. We have recently escalated this issue to see if we can at least get a fix in to stop crash from happening.
To clarify, when LPV is on and if you are starting up editor with basic level with two chairs statue with glass and that table. If you click on glass translucent material it will crash editor.
If you’re getting different results, please list your steps to clearly reproduce error and I will test it out to make sure it’s not same issue.
This is actually just a straight-up crash when loading editor before editor is even responsive.
All I’m getting in callstack is:

From logs:

So I did a little more digging and found cause on my end:
If I end OVRService_x64.exe, everything starts up and works fine, including LPVs.
I initially tried removing nvwgf2umx.dll, which then led to a crash in OVRDisplay64.dll. Then I figured it might have something to do with OVRService_x64.exe, killed that and lo and behold editor with LPVs enabled works just fine.
Obviously having editor crash if I have OVRService_x64 running isn’t ideal, and to my knowledge LPVs were recently fixed (4.3 or so) to work in VR/stereo mode - so I’m not sure what root cause is.
Hopefully that information helps!
EDIT: fix may actually be result of using power button to turn Rift off, rather than ending OVRService_x64.exe. Rift is currently set to Direct Mode. It definitely has something to do with Rift being either on or enabled.
