Newbie: Error loading server extension jupyter_lsp


I just installed Anaconda on an M2 Mac and I am seeing these errors when I open Jupyter notebook. The Notebook itself does open. I am new to this, please explain in simple terms.

Just installed Anaconda myself and got exactly the same thing when launching Jupyter.

I’m having the same issue. Has anyone one came up with a solution to his installtion issues?
