Discussion:
Hi @SubjectivelyCoolGuy thank you for the feedback! I tried to reproduce this error but I was unable to 🤔 Maybe there are some other steps that could be needed to reproduce this? In case you are able to reproduce this reliably, could you submit here a GIF or video showing the steps you are following to trigger the error please?

Any other info in order to reproduce this is greatly apprecited, let us know!

Edit: Checking seems like a similar traceback has been reported before at https://github.com/spyder-ide/spyder/issues/20894 but there is not much info beside checking if a possible reinstallation helps 🤔  

@dalthviz, perhaps we should catch and pass on that error because it doesn't seem to break other things.

What do you think?
I guess we could do that (I think in the past that's has been the approach to handle such `RuntimeErrors`) :+1: Still, it could be nice to actually understand what could be causing this
