When I try launch it I get this long error:

How can I fix this?
Started seeing this after the installing the 6.5.5 version of the notebook packa
…
ge for the python kernel. Unclear exactly what's causing it currently though.
While this issue was caused by switching to 6.5.5 (through the RC1 build) it also affects stable so seems to be something related to the packages themselves.
Failed to change kernel. Kernel SQL will be used. Error was: Notebook process exited prematurely with error code: 1. StdErr Output: Traceback (most recent call last):

Additional info:
1. Here's the PR that introduced the line that's failing : https://github.com/jupyter/notebook/pull/5957
2. Changing line 1411 in `$(Python)\Python38\site-packages\notebook\notebookapp.py` from
`'jupyter_server.contents.services.managers.ContentsManager'`
`'jupyter_server.services.contents.manager.ContentsManager'`
seems to fix the issue.
A workaround for now is to do the following and downgrade the ‘traitlets’ package:
pip uninstall traitlets
pip install traitlets==5.9.0
Hi! Problem still not solved for me: PermissionError: [WinError 5] Access is denied: ‘c:\program files\anaconda3\lib\site-packages\traitlets-5.1.0.dist-info\COPYING.md’
Please help
