MOGRT freezes playback in Premiere Pro on Apple Silicon

Question

Using the latest version of Premiere Pro (23.6.0) on an M2 Apple Studio, running the latest version of OSX (14.0). Loading my simple lower thirds MOGRT freezes playback, I get maybe two seconds of playback sometimes 10 seconds, or maybe some scrubbing over the graphic, and then it freezes the playback window on that frame. I can still use the UI elsewhere, but the playback screen stays the same and I cannot play, I have tried many versions of AE to export from and PR to playback including the betas, resetting preferences, and obliterating caches, to no avail. The only fix I found was launching the Intel version of PR, this has fixed it although, obviously I would prefer to keep the performance of the Apple Silicon version of the software.

Any ideas on how to fix this would be appreciated.

I cannot attach the MOGRT but I have attached the aep. Thanks.

In the latest version of AE this is still not working, on either the Apple Silicon or the Intel versions. I have narrowed down the issue a little further after remaking the motion graphic template from scratch in today's release of After Effects (24.0) to see if it would fix it. This still freezes playback, unfortunately. However, I have noticed it only freezes playback when being played over RED Raw .r3d files. If I hide the track with my r3d footage it works. So the combination of the MOGRT with .r3d video is breaking playback. I would really appreciate any updates on this bug?
