The errors above were due to misunderstanding the Vision OS project setting that generated headers. I had ticked this due to it making the “Vision OS” build capability suddenly exist and assumed incorrectly it was needed.
Instead the solve was to simply tick on platform support. Then from there it was a process of working around some errors on Main and getting plist permissions in.
I plan to attempt this on a more stable engine with 5.4 source and I’ll try to update again. Thanks all.
