ProRes Plugin doesn't show up, but it's activated (AvidDN same)?

Working on UE5.2 and a Macbook Pro, 16GB Ram & M1 chip.
I’ve installed the ProRes Plugin, uninstalled, restarted, imported into a new project - the whole deal. But it won’t allow me to render into a ProRes .mov file - the option just doesn’t show up. Same for AvidDN… any ideas?
