It sounds like Dirk was on the right track in comment #2 and the kernel
spent a full minute trying to get it working:

It seems other people have been having the same problem with USB
Bluetooth and Wifi dongles for years and the best place to track them
all is probably bug 1791389.

Title:
  [mt7925e] bluetooth stopped working after latest update

Status in bluez package in Ubuntu:
  Invalid
Status in linux-hwe-6.14 package in Ubuntu:
  New

Bug description:
  I updated this morning. Bluetooth immediately stopped working. I check
  my computers bios settings and it is enabled. It appears to have been
  caused by the update. It has disappeared as option in my deskotp
  settings, I simply see "No blueooth found" in the settings panel.  I
  can't identify the exact package that I updated. I accepted all the
  updates, rebooted, and at that point there was no more bluetooth.

  $ lsb_release -rd
