thats a good one… so, one possible issue less…
I not understand what’s different in your case, compared to my system. These are both very similar…
Win10 20H2 (19042.906) / i7-8700k / 64GIG RAM(2666) / 2080TI ( ASUS Strix… ) / corsair ax760 / nvidia 465.89 / dxdiag 10.00.19041.0546 / HAGS off
Why does it run fine in my case 
Have you any other addiational software running ?.. e.g. is somewhat auto-started related to the VR software ?
EDIT:
and an update. My friend let run the PC in main-menu for around 1.5hours without a CTD.
