Face time camera not working on Sequoia 15.3.2

Hi all, I have just installed Sequoia on my 2015 MBP a1502 with OCLP 2.2, everything seems fine except FaceTime fails to engage the internal camera.The strange thing is photo booth does works fine (internal cam) AND I somehow managed to get FaceTime to use my iPhone as camera too.

its really a bummer cuz the machine feels snappy, better then Sonoma to be honest. Is there anyone had the same issue? did you find solution ? thanks.
