Importing library in PyCharm Python Console raises ModuleNotFoundError

[guruappa]

Hi guys,

I was trying the library out in the PyCharm IDE. Whenever I try to import libraries, it is throwing the ModuleNotFoundError for _testcapi. I did read in one of the closed issues that this is no longer an issue. But I could not find a working solution to the issue on my computer. I tried reinstalling the library multiple times. Any help would be much appreciated.

I am trying the library on Python 3.10 on Fedora box.
