Suddenly bluetooth was disabled and until now I can't enable it again. The
evening before there were updates, also related to bluetooth and wifi but since
the laptop was okay for a few hours until it happened, I can't imagine it was
caused by the updates. I restored a Timeshift backup from before installing the
updates, but this didn't change anything.
