Canon R6 MKII No Longer Tethering

After an incredibly long wait, the R6 MKII was finally supported for therhered shooting in LRC. Was working perfectly fine a few days ago, and now it has mysteriously stopped. I have tried everything from updating camera firmware, updating to the  version of latest LRC, changing USB ports, changing cables, restarting PC, restarting camera etc etc, and nothing is working. Am constanstly getting the "Detecting Camera' spinning wheel. Connected my old 5D MKII and it had no issues. Can anyone supply any assistance here? 

Thank you
