H265 renders are still broken in update 23.2

Since update 23.1 I haven't been able to export any video with the h265 codec. All the video files are unplayable or don't allow the video to be scrubbed through.

To elaborate, the files will play but stop playing the moment I try to scrub through or click anywhere on the timeline. I'm using finder's preview feature but even opening the files in Quicktime or VLC have the same problem. Most of these renders are over an hour long, so simply letting the video play to see if the render is successful is not an option. I've tried changing many render settings to see if I could remedy the issue with no success. H264 works just fine. Prores in both 4444 and 422 flavors work fine. 

I've tried every update, uninstalling and reinstalling, and IT even upgraded me from an M1 Max Macbook Pro to M2 Max during this time so I had all apps freshly installed with only my personal files being moved over to the new computer. I'm stuck at version 23.0 of the app until this issue is fixed.
