Several days passed, and everything seems to be fine with bluetooth. I don't
know why the first day after update was so terrible.
I don't know if it was something I did, or it just started to work.

Title:
Bluetooth isn't stable - 5.13.0-35
Status in linux package in Ubuntu:

Bug description:
Ubuntu 21.10 (Impish)
Bluetooth disconnects after few minutes, after kernel upgrade from
5.13.0-28-generic to 5.13.0-35-generic. After connecting, it disconnects again
after few minutes.
To connect again these commands helps:
