AX211 stopped to pair keyboard and mice

Hi ,

I am facing an issue when AX211 based laptop (HP Elitebook 1040 G10) at some point starts to refuse (even can't find while scanning) pair bt keyboard and mice (tested with Logitech MX Keys, MX Keys Mini, MX Master 3, MX Anywhere 3S ). All these BT keyborads and mices are work perfectly previously and works as expected at my Lenovo Thinkpad X270.

Please help.

My environment is the following:
