Thanks for the logging Brian, our developers have successfully identified the issue and released a build, which can be requested by getting in touch with support.


An official fix will be rolled out in the coming weeks.


Could you kindly upgrade to .NET Framework 4.7.2 (install all updates for .NET) and then reboot if necessary and try the backup again please?

I'm already running .Net 4.7.2.  I ran the repair of 4.7.2, and rebooted, but it still failed with the same error.
