Thanks for that @bitwise, sorry for the delay replying but I didn't get any notification of replies!
I've tried rolling back recent updates to try and solve the problems, and one of them turned out to be the 20H2 update, even though it said it was installed today, which is nonsense, it was installed several weeks ago!
It then reverted to 2004, but offered the 20H2 update, which failed with the same error (0x80070003).
I ended up having to do a system restore, which has put it back to 20H2 19042.630.
The KB4586853 update is now being offered again, but still failing, same error.
I have now tried doing an in-place repair, but it's not letting me keep my files and apps.
It says "Your files, apps, and settings can't be kept because your current version of Windows might be installed in an unsupported directory (it isn't), or you're trying to install an older version of Windows (I'm not!)
So, what do I do now?
I'm NOT doing a clean install!
