PAL Export takes forever (since media encoder 22)

Hi All,

since the upgrade to the latest media encoder 22, some reencodes from PAL ProRes422HQ to PAL ProRes422HQ take forever, like 30 minutes for a 1 minute clip. I have an older version of 21 on another machine, and it is encoding the identical file from the identical location in a few seconds.

This is quite annoying. Any Clues/fixes?

Here are the details of the file:
