Hi! I am Ahmer. I had issue with my bluetooth dongle that was working fine with kernel 5.11, but then it broke again. But thanks to the effort of the linux community people it worked again. But, it doesn't work now with kernel 6.0.0 and newer. This is the output of "sudo dmesg | grep Blue" ,hope this helps:
