Hi. I’ve been trying to install PsychoPy on my Ubuntu 20.04 laptop. Installation process (PsychoPy, wxPython and PsychToolBox) was easy but the problems started afterwards. The first thing I noticed was that PsychoPy was not on the program list in the Ubuntu’s „main menu”. It was strange because last time I’ve installed it on Ubuntu, it was there. The program starts when run from the terminal but it has a glitch instead of the icon.
When I try to access preferences I get the following error message:
Traceback (most recent call last):
File "/home/jakub/.local/lib/python3.9/site-packages/psychopy/app/themes/_themes.py", line 813, in _loadBitmap
im = wx.Image(filename)

During handling of the above exception, another exception occurred:

…and this appears in the terminal:

I’ve tried to use other python versions than my basic 3.8.5 (3.9.4 with PyGame, this alone was painful) but the result was the same. What am I missing here?
It wouldn’t be much of a problem but I that’s what I get when trying to run an experiment:

…no matter what python version I use. What can I do to get it to work?
