Can't save work please help! (need for a-level)!

Every time I try to save my work, on my laptop or at school, It pops up with this PNG of a white ball with different colours around it (Image attcatched). I can’t scroll on this or anything this is literally it, when I press save this picture comes up. I don’t have the first clue on where to start to fix this so any help will be much appreciated!! I need this for my A-level so I can’t lose this work.

does this occur with all files or just one?

How large is the file? It may be too large.
