VR crashes when entering Options>VR

[GayCavalier]

Symptoms:

Every other VR title I have works fine...

Whenever I attempt to enter the VR menu (in options) during a mission, DCS will crash.    Also, If I enter the VR menu while in the main menu prior to going into any mission, then DCS will crash at the "Mission Load Complete" point.   Happens regardless of the aircraft.

This happens every. single. time.

I had originally been running OpenComposite (OpenXR toolkit and PimaxXR) successfully for some months without issue, and then this started last week.   At first, I thought a PimaxXR update had caused it, but it appears to be a basic DCS thing as it also happens on Steam alone.

I've attempted complete reinstalls of everything - finally stripping everything back to a bare OS without Nvidia drivers and building up from scratch (after deleting any install folders or remanent files or registry entries).

Currently, I've found that even a fresh install of DCS either before or after installing PiTool and SteamVR causes this.  I've tried this with 3 different clean Nvidia driver builds.

I didn't think I needed it, but i've also created a fixed 32Gb pagefile on OS drive, and that did nothing.   I've cleared fxo and metashaders a number of times and deleted the whole savedgames\DCS folder (to reset) too.   I've lost count of the number of times i've verified the DCS game files..

Settings in DCS are 'virgin' i.e. untouched from clean install.

I am at a loss - this came out of nowhere about 2 weeks ago.  Any help would be appreciated.

Environment:
i9 11900kF, 64Gb RAM, RTX3080, all Samsung 980Pro SSDs (double checked integrity with Samsung Magic).  Pimax 8kx.
Win11.   Latest Nvidia Drivers (also tried rolling back to previous two).  PiTool (latest).  SteamVR (non-beta) latest/repaired.   Steam DCS slow repaired.  No mods whatsoever.

... i'm going to nuke the site from orbit:
- blank OS SSD,
- uninstall and delete any trace of DCS (Steam)

..and start over.   This is clearly not a Pimax or Steam thing because everything else works perfectly.


I'll report back.

OK.. that didn't work.   Now i'm totally out of options.   See new log based on going into F18 training mission, clicking options, and then "VR tab"

A common theme appears to be this in the log files:
2023-01-19 00:54:28.679 INFO    EDCORE (Main): # C0000005 ACCESS_VIOLATION at E4D70C3D 00:00000000

The 0000005 Access violation can be found in all of my logs post the "trying to write dump information"  I'm not sure if this is pertinent to the issue.
