I'm sorry for the mess OP. Unfortunately they are trying to push the premium/paid version of onedrive to every windows 11 user, since they also limited the backup functions of previous windows versions to make you pay an extra fee if you want to keep all your data secure on their servers. As I installed Win 11 I also had an horrible experience with OD, I said to myself "let's try it" and that frigging app starting moving all my files from my laptop and my desktop to the cloud, uploading gigs and gigs of data without even asking for it. As I wanted to stop the process, all the files that were once on my physical drives got deleted and it took me literally hours to go back, I had to re-download everything from one drive, move all the files I had on the desktop to the laptop, restore all folder paths that were in the meantime replaced with those from onedrive, and in the process I have also irremediably lost some files that I cannot find anymore. Luckily nothing of great importance, but it could have also been sensitive data and documents.
So beware, don't touch that shit.
