"Interpret Footage" is broken in Media Encoder 24.2.1

Media Encoder 24.2.1.

Attempting to encode a Quicktime ProRes 4444 W Alpha video from a 2000 frame image sequence. 

If "Interpret Footage" is used with "Assume Framerate" (24fps in this case), the frames only encode properly partway into the finished video. At some point, the motion gets stuck on a single frame, and that single frame is encoded into the remainder of the video, frozen in place until the end.

Previous versions of Media Encoder tested and do not have this issue (Currently switched back to 23.5 which works fine)
