Looks like you have a callout to a MainConcept MP4 file/Event and that in turn is calling up a Mainconcept CODEC. Any chance you could isolate and remove that MP4? Or even replace it with a SONY MP4 render instead?
Just as a test “project”, try and remove that/those files and see what gives. Nasty.
Do you have any VST Audio plugs on the go? Maybe you need to rescan your VST folder/s?
