Hi, I just downloaded Psychopy on my personal computer and it crushes whenever I try to open it. I get an error message which I have attached below (error.csv).

I managed to open it, but it crushed when I tried to change the theme from default to “minimaldark”. I wasn’t able to do anything else. I tried re-downloading but the issue persist. It’s the whole of psychophysics that doesn’t open, not just coder/builder.
