Cloud file doesn't recognize me as the file owner

I made some illustrator files several months ago and saved them to the cloud. Now I am trying to open them and it says "Can't open file. The account you signed in with doesn't have access to this file. Contact the owner for more info." I am the original creator and I have an adobe account using one email that has both a personal account and a school account (which I can't remember if I've ever used this). The files appear in-app under "Your files" but if I go to assets.adobe.com it says "You have no cloud documents." Since I made them I've gotten a new computer and my original subscription ended and I am currently on a 7 day trial on my personal account. Also I'm a student and my institution paid for the subscription originally. I don't remember if I made the files after being signed into a personal account or a school account. When I'm signed into my school account if I try to go to assets.adobe.com I get: "Error 401: Unauthorized. You are not authorized to access this site." I'm just trying to make small changes to these files and recreating them from scratch would take weeks. 😞

Clearly the ownership of the files has gotten mixed up somehow since I made the files but I don't know how to check who Adobe thinks is the owner.
