I am creating a chess game that uses multiple different python files. I am met with the error of video systems not initialized, relating to a pygame.display.update(). I have tried so many things to get initialize the program and am unsure of the issue. Could the issue be to do with a missing line of code or something?
Already attempted reinstalling pygame, making sure there are initialization s for each file.
here is the executable file, but not the other related files for the program, I can attach these if necessary: Here is an extract of the program:
