Info logs and just the error spew are just about useless. Info logs are not debug logs. Please review the link from the post template linking you to the wiki.

It looks like there is some non video-file in the Office that is causing an issue

Thanks for the heads up; it seems multi-part/file episodes that Sonarr can’t handle are the problem.

I’m working through all the errors and joining multi-parts into single file episodes using MKVToolNix and hopefully that will fix everything once done.

Sonarr supports 1 file many episodes, but it does not support many files 1 episode
