My Rift S still worked just fine after I updated to Windows 11, mind you this was in 2022 when I did my update, so maybe the oculus program may have been updated.
Works fine if not better. I play fine at 30hz via OTT with settings on high and res 100%. Also using the OpenXR tool kit where I have it set to FSR and still 100% with 20% sharpening and world is 85% (makes cockpits much smaller and more realistic in size to your POV especially fighters.
I was running Win 11 pro upgrade with a 2070 Super and Ryzen 3800X (now a 5950x)
