UE FFR Glitching in XR PAssthrough Build

Hi Guys, so i enabled FFR in  my XR Game, i packaged it as Development if its matters. I use fixed Level 2 FFR , and i get better Perforance but in the Field where FFR steps in around the sight Things get Frozen and its Glitching. Its liek it wont Update the Area around the Eyes. (ITS ONLY IN THE LEFT EYE) What could it be?

not my video!

but its exactly this:

in Short; the fovea works fine but outside of it it’s glitching, like showing static objects of the Level and are not updating, left eye only.
