I had this problem, it kept saying file to big or something. All I did was cropped the pics and then it seemed to work. I used the windows picture viewer or gallery programme to do it(can’t remember what it’s called, but it’s not a special programme, its one that was already on my laptop) there’s an edit option, I clicked that and then it loaded it up and I found the crop option in the top toolbar and that seemed to work for me
