Windows 10 RoboCopy is reporting a failed copy in the summary but not in the details even with /V and /Log. How do I fix this?

[isgdre]

In Windows 10 robocopy is reporting a failed copy but the detail log looks fine so I can't fixed the problem.

Total Copied Skipped Mismatch FAILED Extras
Dirs : 1101 0 1101 0 0 0
Files : 5369 111 5257 0 1 110

When it fails it returns error code 11 ( FAIL XTRA COPY )

This started happening With the last update of windows 10 (20H2). It seems to be happening approx every other day. What can I do to find out what's failing?

Here is the command line I use to run it;

robocopy /V /JOB:$JobFile $DriveToBackup $BackupDestDir

Here is the job file. As you can see the /V and /Log+ option is on (the common solutions you can find on line).
