I have the same issue from yesterday since I upgrade to pb2 on my iPhone SE 2. Reset the AirPods pro and AirPods serval times but it still doesn't work when I listening to the music except the phone talk.
also, Beats, Bose QC30 and pixel buds they shows the correct connection to your iPhone but music didn't play in your earphone. really wired.
btw, I have iPad pro installed 13.6, it works well.
