imo win 11 is almost like win10 21h3 in essence, except for the graphic user interface change (MS skin).  are you able to try compatibility mode when you install Oculus Rift S software (and exactly what software you plan to install?).  right click on the exe and choose compatibility for Windows 10 if that option is available.
Bought an Aurora R12 for my son this past Christmas and, to our dismay, the software he needs for his Oculus Rift S hasn't been updated for Win 11...and it looks like there's no real hurry on their part to get this done. Seems odd to sell a gaming PC that ships with Win 11...VR is a thing and Oculus is a big player in that game...and you can't use it with Win 11. Am I sort of on my own with this issue?  Since it shipped with Win 11, I can't roll it back to 10...
