I had the same issue.
The exact cause is unclear, but reverting to a previous stable release resolved the problem.

You seem to be on a 2year old version of the extension, so your not actually reverting to an older version, actually you’re upgrading your extension to a much later version

please ensure you keep your extension upto date to get around such issues
