I am unable to open any of my past Jupyernotebook or python files I have and I get this error for them:

Unreadable Notebook: C:Users[mypath]mainmain.ipynb OSError(22, 'Invalid argument')

[mypath] is the part of directory I deleted from above here.

I tried solution by this post, but still have the same issue.

This is also the error I get opening a .py file

Error! Traceback (most recent call last):

Same issue persists opening the files via jupyterlab.
