Unifi Protect can't change detect settings on G4 cams any more

On G4 cameras, if I try and disable person/animal/vehicle detections I get this error:

It works OK though on on the 1 x G5 I have.

Versions:
Protect 5.3.41
HA 2025.4.3

I’m sure this was working recently (I have an automation which disables/enables these switches) - but I could be wrong…

I’ve tagged this as third-party integrations, but I think Unifi Protect may be core now?

I’ve logged a bug
