Okay, last comment, sorry for the spam, I had to change computers again.

I tried changing USB ports on my desktop PC but bluetoothctl and list don`t
find any device, no matter what USB port I tried.

To make the btmon log short I restarted and only reconnected the dongle once.
When it says ~delete index~ is when I removed the dongle from the PC

Bluetooth monitor ver 5.61

In the two last lines it resets and closes the index even if I don`t do
anything. I hope I could help.
