Hello !
Usually, when you cancel your Microsoft 365 subscription, your files are not deleted immediately. Your account is frozen because you're over quota, but you can still read and download files.
In your OneDrive account, go to the Recycle Bin and see if everything is still there.
You can also try to restore your OneDrive space here : https://onedrive.live.com/?v=restore
Looking forward to your answer !
