"Files/Exprot and select exprot as full body morph while having save binary morphs selectes"

You don't need to use external binary morphs on in prefs in order to use Export: Morph Injection. This is a holdover bit of lore and was only necessary in the old days when you would save the morphs from a saved cr2 and create a pz2 for pmd injection. I used to defend binary being on in prefs back when people were very wary of it (PZ3 corruption etc) being activated but now with Export: Morph Injection I just leave it off and go with embedded. The overhead is negligible unless you are using a fully loaded V4 or something...
