Issue with opening a python file

[Daniel Ding]

Hello, I'm relatively new to python.
Recently I have been receiving errors every time I attempt to open python files. When try open them, it sends me directly to the 'Modify Setup' window. Clicking on repair or modify does not fix the problem, it simply goes through the repair or modify process and then closes, whilst the problem still persists.  Is there any possible fix for this?

Thank you
