@APitou there is a known issue (fixed in 1.42.2) when the ‘Maximum simultaneous background video transcode’ setting is set to unlimited. can you try changing that setting to anything else and see if that resolves your issue?
@gravee first off I would 100% immediately update to 1.42.1.10060 to avoid the security vulnerability. second while I don’t remember the nature of the issue off the top of my head its likely you need to clear your queue and start again. I would back up your database, clear the queue, and then try adding 1 to 2 more items to see if they resolve. with the backed up database you can always restore your queue if this does not resolve the matter
