The left menu in gui disapeared, and I can't stop the nodes properly - I would like to avoid hard shutdown of the (baremetal) server
Is there a way to recover in a clean way the GUI?

Thanks

Actually I couldn't wait and reloaded the server.
Now I can acces to the "File tree" page, but I cannot start the lab I was working on when I got the error message (I get briefly the same SLIM error mesage, then the "file tree" page show up again).
The other labs can be started without any issue.

Any help would be greatly appreciated.
Thanks.

That single lab is corrupted.
Btw did you use lab lock for it?
If yes, then you can export that lab and send to me, I will look if something can be done.
