Psychopy fails to launch

I have just downloaded the latest version of psychopy on a Win10 machine, but can’t get it to launch.
Following instruction from the website, then attempted to launch it from the command prompt with

PsychoPy3\python.exe -m

I got the message below - it looks as though there is an issue with OpenGL towards the bottom.
Any suggestions for fixing this?

I guess that I must have done, as I used it for 2nd-year practicals in feb, but I don’t recall how it was resolved.
