Suddenly hardware encoding no longer possible when exporting media

I have a MacBook Pro M2 Max, 12 CPU cores, 38 GPU cores, and 64GB RAM, running MacOS Ventura 13.5.2.

This summer I have edited a lot of videos taken with my Mavic 3, 5.1K, Apple ProRes, 422HQ, and exported to 5.1K format using hardware encoding. I have proof, I have the files that I exported.

Suddenly I can no longer HW encode video files to match the same settings as my Mavic 3 footage.

Please do not ask me "if I have the latest... blah blah". Instead, if you are really interested, try to download an example I've uploaded to OneDrive (does not require login), and see if you can encode using HW encoding to match the same settings as the file.

The test file can be found here https://1drv.ms/f/s!ApwvJiPkGv7shPRryrFYuLoUpB-R9A?e=aayPXY (click on the file, and choose DOWNLOAD).

What has happened?

Thanks

I forgot one more detail:

Your export resolution is too high for hardware encoding in H.264. Maximum supported resolution for hardware H.264 encoding is only 4096x4096. The 5120 frame width forced software encoding. With a 5k frame width, you must use HEVC in order to hardware encode. You cannot hardware encode 5k video to H.264 no matter what equipment you have (at least with Premiere Pro). 8k H.264 hardware encoding is not currently supported in Premiere Pro.

Ok, that's a long-GOP H.264 encode.

In the Preferences, there are a couple options for doing H.264 encodes, what are those set to?

Everyone's mileage always varies ...

Thanks for your reply Neil, though I'm sure the culprit is somwhere else totally - remember, this is something I suddenly can't do anymore - so what has changed?

As requested, I have attached my encoding settings.
