I actually managed to fix it! You see, I reflected on the fact that it mentioned that I lacked the access to the file, and I shared the file, with myself! It worked, and now I am not going to do anything else with it for the rest of the week because I don't want it to break again. This event has truamatised me. Hopefully this helps someone else, I was freaking out for a good thirty minutes before I came here.
