This is the corrupted I mean

[Ad163]

this is the error I got after I installed and launch my Jupyter notebook again Traceback (most recent call last): File "C:\ProgramData\Anaconda3\lib\site-packages\notebook\traittypes.py", line 232, in _resolve_classes klass = self._resolve_string(klass) File "C:\ProgramData\Anaconda3\lib\site-packages\traitlets\traitlets.py", line 2015, in _resolve_string return import_item(string) File "C:\ProgramData\Anaconda3\lib\site-packages\traitlets\utils\importstring.py", line 33, in import_item module = import(package, fromlist=[obj]) ModuleNotFoundError: No module named 'jupyter_server.contents'

During handling of the above exception, another exception occurred:
