Running updated Adobe 2021 on AE and Media Encoder.
Only encountered this problem once switched to new Mac Pro. Previously worked on a 2014 Mac Pro.
I am exporting an LED board - (built at 90px high in AE) at 70px high and cropping the source in Media Encoder. As soon as encoder gets to that file it freezes and slows down the whole computer making it almost unusable.
No markers present in any of the creative - as I have seen this error may be caused by markers.
Have had to force a reboot numerous times now.
