I use a rift for dev
I am able to use the template fine
I have packaged win 64 and Quest with no probs.
if you “add” the vr template you need to import your mappings
you need to make the base project from the vr template first not add it after or you will have probs
I also only use open xr and have steam and oculous plugs disabled
the suggestion of deleting intermediate is valid.
