Unhandled Internal Error in Builder when opening Plugin Manager

OS: Windows 10 22H2 (OS 19045.4780)
PsychoPy version: PsychoPy v2023.1.0.
Standard Standalone?: Yes
**What are you trying to achieve?: I try to open Plugin Manager and get an ‘unhandled internal error’

What did you try to make it work?: I have tried tracing the error message back to the specific files, but am unable to even open the files in python for some reason.

What specifically went wrong when you tried that?: Whenever I try to open the ‘Plugin/packages manager’ I get the following error:

Traceback (most recent call last):

Does anyone know how I could fix this?
