You’ll see here that error (No module named 'jupyter_server.contents') is posted as an issue and has suggestions for fixing it. (There’s also here and here that probably would come up when you are searching that first ModuleNotFoundError error that comes up. You may want to peruse the contents, especially in light of my next paragraph.)
Related: The first occurrences of lines starting ‘File’ in that traceback indicate you’ve mixed and matched and made things complex on your system. The first one links to the Anaconda distribution as the source and the next two are independent of Anaconda. Mixing-and-matching like that can make things harder going forward.
