Psychopy encountered an unhandled internal error (changed )

I am running psychopy on a new computer (win7;64) and I get the following error. I have tried using four versions 2020.1.3, 2020.2.10, 2021.1.3, 2020.1.4 and all have the same problem. This is so upsetting to me!

Can you try a different version of Windows 7?

Thanks for your reply. This computer has many important documents of others，so I can’t change the windows version easily.
