Can't log out of Manager, then can't log back in, then can't install with upgrad

Uninstalled Archivist package which removed ArchivistFurl from the Plugins folder. We’ll see if the the problem goes away.

I have been running all day, about 7 hours, without a single crash so it looks like Archivist may have been the problem.

Thanks for your help Mark!

Disabling Archivist drastically reduced the occurrence however the problem still exists on a much less frequent basis.

One scenario that has failed twice is creating many new template variables in succession.
