I'm using an old version of Anaconda (Anaconda3-2019.10-Windows-x86_64 on
Windows 7 Pro)
It was running fine until recently when it stopped working.
Whenever I try to run it crashes, issuing the following error. I've removed
and reinstalled Anaconda (using ReVO uninstaller) a number of times and
reset Spyder using "spyder --reset" command but nothing helped.
(base) PS C:\Windows\system32> spyder
Traceback (most recent call last):
