Ran into the same problem, after some digging this seems to be an issue with Cython.

Unresolved using the newest python release 3.10.2, pandas==1.4.1 & numpy==1.22.2

This only happens in the debugger, please try running your code without the IDE debugger.

This will be released in the next Cython release, best to follow the below two issues to get notified once resolved:
