I have found the cause and am posting here for anyone else with the same issue.

The new NVIDIA App has an option in the settings which, when switched on, places this lock file in the video folder. I just switched the option off and the problem was resolved!

When synchronising I get this error message and the cause is that it is locked by another process: NVIDIA App [C:\Program Files\NVIDIA Corporation\NVIDIA App\\CEF\NVIDIA Overlay.exe]. See attached.

Can anyone suggest a solution?

10:45:12 Error: Cannot read file "C:\Users\Clive 2\ntuser.dat".
The file is locked by another process:

Registry
