Before Christmas, I decided to completely rebuild my MagicMirror.
The mirror works fine so far, but now I have the problem that I can no longer start and see the MM as another instance on my PC - it worked before on my old mirror.

Here is the output when I try to start the MM with “npm start”:

chef@pi5:~/MagicMirror $ lsb_release -d
Description:	Raspbian GNU/Linux 11 (bullseye)
chef@pi5:~/MagicMirror $ npm start

> magicmirror@2.26.0 start
> DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js

Any ideas?
