Posting for the benefit or others... Yesterday I updated my Radeon driver (for 5700XT) to the latest/current, Adrenalin 21.6.1, released 6/21/2021 and later found that my Oculus Windows app and link was broke. It exhibited 2 symptoms, one was the Can't Reach Oculus Runtime Service message and the other was the Oculus Windows app recursing over start and crash. When I could the screen that popped up for a second it had the Oculus isn't compatible with this systems hardware.
I did many repairs, unintalls and reinstalls and even factory reset my Quest 2. After much googling, diags and attempts I recalled that I updated my video driver.
I removed the current Radeon driver and reinstalled the last driver released in April and all is well. Seems the lastest Radeon driver is not working with the Oculus apps/service.

No real surprises. AMD has always had more PCVR problems imho. Maybe this will improve in the future.
