I'm not saying that this is related or the solution but I figured it's worth mentioning to help move forward with finding a solution.
I encountered a problem in windows 10/11 when I would use the transmit button on my VR that the framerate would drop down to less then 5 fps for the duration of the button press. I'm a little foggy on exactly what it was but as I recall I had to open windows sounds settings and go to a specific tab and leave it open. When I had this open it would work properly and the screen would not freeze. I guess it was a "random feature" in windows that caused this.
The reason I bring this up is that it may be possible that there was a a windows update in the timeframe that this started happening and as people are getting the updates it is affecting more people?
