hci0: Failed to read codec capabilities (-22)

Question

During OS startup I see an error

/dev/mapper/vgubuntu-root: clean, 1438749/31105024 files, 57458210/124394496 blo
cks
[    3.516030] Bluetooth: hci0: Failed to read codec capabilities (-22)

The most interesting thing is that I see this error on the display connected to the laptop if I expand any application to full screen (on the additional display)! Everything is fine with the laptop, the second display is shown in the settings, but I cannot interact with it, as the display shows this error for a while and then turns off (it continues to be displayed in the screen settings, but I can't interact with it - no signal!)

Please help me!

I removed a ton of extra software, tried reinstalling adapter drivers, but it didn't help. bluetooth service looks just fine:

I think it was two different problems. I fixed the error about bluetooth with reinstalling amdgpu driver.. I don't know why and how. But here is the link: https://repo.radeon.com/amdgpu-install/latest/ I still have a problem with additional display, but now it just turns off without error message. and it happens only if I expand any app on full-screen. funny.. — mnzsyu, Aug 05 '23 at 09:50
