I too am getting this error despite factory reset, etc. I am not even trying to cast - simply wanting to screen record but I get this error message and then it eventually starts recording but the timing of the sound is off by about .5-1 second. Happens in all apps, although I did try uninstalling and reinstalling those apps anyway. Any chance a fix is coming?
This issue is not yet addressed on the link given for casting. It has been around for more than a month.
When I did a version update to 220.127.116.11......done in either late June or early July, 2022 (not sure of the exact date) it *broke casting* to both Windows and Mac PCs. This function had worked perfectly well until then. No fix has been identified from Oculus support yet (as of Aug 2 2022). This makes the headset useless for guided demonstrations and use. This is a critical failure. Please advise on fix or how to back down to an earlier version.
