I've just run the Pre-Scan on my Win 10 1909 and it came back without error.
I then opened the repairs in normal mode and checked to see if it had created a registry back up - which it did.
I then went into Event Viewer and saw this error which it has been producing of late and of which others have reported -

I've reported this to Shane but haven't had any feed back on it yet.
