Psychopy 2023.2.3 crashes on startup (Windows 10)

OS Win10 Pro 64b
PsychoPy version 2023.2.3, but tried also with 2022.2.5 and same problem occurs

Standard Standalone? Yes

What are you trying to achieve?: Open psychopy on university-run computers (all identical, same installation).

What is the problem? On startup, the three windows (runner, coder, builder) open, but as soon as the tips window or the version compatibility warning window is closed, the app crashes. If I am quick I sometimes manage to open an existing experiment in coder, but the app crashes right after that, before I can start the experiment.
This is NOT a problem with the experiment, which runs fine on other computers, but with the installation/running of psychopy on these specific computers.

What did you try to make it work?:

What specifically went wrong when you tried that?:
Below is the most complete last app load file I could get (there is no time to read the error messages during startup as it crashes too quickly, and often before the error messages are done being written).
I have tried googling any of these possible errors but can’t find anything helpful. Any ideas as to what could be causing the problem would be appreciated!
I suspect it could have something to do with the fact that those are university-controlled computers linked to each other (I do not have admin rights to run the programme, but the installation was done by IT so with admin rights).
