Hey @duggar, thanks for reporting. Please close Spyder, open the Anaconda Prompt and downgrade qtconsole (one of our dependencies) with the following command:

conda install qtconsole=5.0

That should fix this problem, but let us know if it works for you.

[ccordoba12]

Some months ago, we did some changes in qtconsole that are incompatible with older Spyder 4 versions. And, unfortunately, we didn’t add a top constraint to qtconsole, which caused this problem.

So, the only solution is to manually downgrade to an older version.
