OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): 2022.1.2
Standard Standalone? (y/n) If not then what?:y
What are you trying to achieve?:
My previously working experiment program cannot be launched when clicking on it. When launching psychoPy builder first and then open the experiment file in it, the experiment was loaded but I received an error message saying “PsychoPy encountered an unhandled internal error! Send the report under “Details” to the developer…”

Below are the “detail” message:

What folder is your experiment in? It looks as though PsychoPy is looking in the same folder as the experiment for it’s README file, but while doing so is hitting a file with a character which glob (the Python package which PsychoPy uses for this kind of folder searching) isn’t built to handle. What other files are in there?

I’ve added some code which may fix this:
