Thanks for your help. I tried all of your settings above and tested. I seem to be able to prevent the crash in cockpit by 1. setting motion reprojection to automatic and 2. going into the menu (esc) before the initial WMR menu start (not required for me after initial run of WMR start).
It definitely seems something resource related. Generally the lower the settings (less resources used) the less likely it is going to crash. This is why I think pressing esc before opening start menu helps when I have settings pushed up.
Will do some more trials. I never had any issues with it in Beta and was constantly using it which is why I have tried to get this to work reliably for weeks. Thankfully your success motivated me to revisit this. Perhaps others will be able to test this with their settings and rigs @CalmEspresso
