Unfortunately you may need to revert back to Windows 10.
Especially if you are dependent on having subs.
Preview OS or application software should be tested in a test environment versus a production environment.
Not everyone has that as an option or capability so the next best approach is to use a second drive that can swapped in or perhaps a virtual machine environment.
So if things do not work out, as in your situation, you can simply reinstall the original drive and continue working (uploading content) as normal.
And as always, ensure that everything important is backed up, recoverable, and proven readable.
