Sound imbalance in Airpods Pro 2 after Upadting to 6A301.

My Airpods Pro 2 got updated automatically on firmware 6A301. Since yesterday I'm facing audio issues like

1) left airpod volume is lesser (checked accessibility settings for balance and its ok)

2) Sound is muffled and bass is very muddy in right side. Left side has less volume but comparatively clear bass.

3) Sound somewhat gets balanced, and sound quality improves after I switch to adaptive or transparency or noise cancellation. But deteriorates as soon as I turn off all these three functions.

4) I tried resetting the AirPods. it works fine after I paired it again but only until I turned on adaptive / transparency mode and again all those sound issues popped up.

seems like a software issue or bug as After resetting and pairing sound quality was okay for 2 to 5 minutes and again it changed as soon as I switched to any noise cancellation modes.

Anybody facing such issue please revert.

and Apple please fix this issue as soon as possible as AirPods pro 2 are unusable now.
