Roll back to windows 10 from 11 before 10 days

I recently got an update to windows 11, so I said to myself "why not?". It didn't take me long to realize that windows 11 is not for me since the update made my PC restart, crash and get all kinds of errors. I didn't know how to go back to windows 10 so I was looking for a video. I found one that was saying to download the windows 10 ISO and I did that (didn't know about the "Go back" feature). While I was downloading it, I found another video about the "Go back" feature and I cancelled the download. However, downloading the ISO made my windows Disk almost at full capacity (you need 25.5GB for the feature) and so I deleted some files with the Storage "Cleanup recommendations" feature. After I made the necessary space, the "Go back" option was no longer available, so my guess is that in this whole process I deleted a required file (?) for it. Can someone tell me if it's somehow possible to use that now? Thank you in advance.
