Adobe is such an unnerving company. If you try to create a new Ingest Present for Premiere Pro on a Mac Silicon using the AME Silicon version, you're out of luck and you will go crazy trying to figure out why the stupid app refuses to create a new Ingest Preset.
If you click on Create New Ingest Preset, you will not go anywhere, the Preset won't be saved, and as a matter of facts, the window that opens is not even the correct one, it shows only a "Save As" button that doesn't save the Preset as Ingest Preset, but strictly as an Encoding Preset, unusable for Proxies creation.
It's a BUG Adobe. And it has not been fixed as of AME v 22.5.
To be able to create a new Ingest Preset, one has to use the INTEL version of AME. Accessible to launch under Creative Cloud app, AME, the three dots on the right, Open (Intel.)
Then with AME Intel running, on clicking Create new Ingest Preset you do get the proper window and the Save button, and it does save your preset as an Ingest Preset that works with Premiere.
That no one at Adobe bothered to check if this worked with the Silicon version is telling.
PS: AFTER you've created your first user Ingest Preset using AME Intel, for some reason AME Silicon allows you to create more and behaves as it should. Maddening.
