We've been through all of this before. Did you actually navigate to the folder as suggested and delete files as suggested? None of what you've posted to date suggests you ever did so.

Deleting Normal.dotm is pointless, as Word recreates it upon re-starting if it's missing.

If none of the normal methods of dealing with such problems, including repairing the Office installation, resolves the issues, you may need to do a fresh install of Win 10 - as previously mentioned - and all your apps. Do back up your data first, though, as a fresh install of Win 10 will erase all your files & settings.
