Command Error upon Export with v3.4.4

Getting a ‘Command Error’ as soon as I chose ‘Export’. (Also had one crash.)
Experiencing with Artemis and Iris.

Hello,

It looks like this is caused by the app trying to copy the subtitle track from the input into the output .mkv container.

Switching to .mov or .mp4 as the export container should resolve this error.

Thank you - will do so.
