Hi I have same problem.
ACER NITRO / Ryzen5600 / 24GB RAM / RTX3060 / win11 latest update / oculus app latest update.
2 weeks ago I have updated win11 (obliged safety security update + meta oculus update).
Since then, oculus quest 2 / 3.0USB killed.
We have some computer with same hardware + win11 (i5, i7, i9, ryzen5600, RTX3060) and all have same problem since then. Oculus Quest 2 doesn't work any more as display, cable link (10GB/s 3.2 Gen2) cables rejected.
It works just with USB 2.0 (380MB/s), 80Hz, resolution dicreased.
It was working with MSFS 2020 perfectly, since upgrades , the oculus quest 2 completely blank with cable link.
Other interesting: it was never worked with air link (WIFI-6 network, latest hardware PC + laptop)
QUEST 2 absolutely work alone unit , cannot be used as VR display , I am very disappointed.
I have IT engineer son, he is absolutely reject Oculus Quest 2 because of lot of unsuccessfull lost time spent to re-alive Oculus , all the META advice tested, nothing valued.
I think, you are not sure, what is the problem , just making advices, maybe any of them will work.
I am very very disappointed !!!!!!!!!!!!!!!!!!!!!!!!!
