Please help, So many errors suddently

Hey, i tried uploading an mp4 directly to the uploads and now it shows so many errors. I deleted the file although the errors still persist. Can someone please have a look at them and suggest what’s wrong.
I did it once today, then it showed an error so i deleted it and the error went away so i tried again and this time so many errors are showing and i didn’t did anything else.
