Hello @mcfate and welcome to the community!

Looks like mentioned file /Users/mcfate/Library/Caches/JetBrains/PyCharm2021.2/caches/names.dat is corrupted. I suggest to clean the PyCharm caches and see if issue will come again.
If it will - would be great to know how it happens. Ideally - describe steps to reproduce this issue.
Have a good day!
