My left airbud in airpods pro got crushed. But sensor is not working

I've Airpods Pro 1st gen. The first one got crushed under something .. may be foot step. But this is crushed and not fully working. It does charge, it does appear in sound/volume settings. Its mic is working and speaker is working perfectly fine.

But none of its sensors are working. Touch is not working and in-ear-sensor is not working.

Do you suggest if I should open it carefully and clean it and check .. do you think it could be only one flex cable containing all of these sensors. ?

Please suggest. Thank you
