Project already open, but the unity editor not showing

I tried multiple solutions like:
Deleting the lockfile.
Restarting my pc.
End task unity editor.

I watched a lot of tutorials but doesn’t seem to work.

I already contacted the unity support but I want to go here if anyone knows how to fix it in the meantime.
