GUYS I FOUND THE FIX !
first you want to update your tvOS to 16.6 from 16.5 so to do that
first click on beta updates -> tvOS 16 public beta -> let it update -> now ur tvOS is 16.6
Then what you wanna do is
beta update-> tvOS 17 public/dev beta -> let it install -> congrats you now have tvOS 17.
It worked for me. Simple yet complicated fix.
Let me know if it worked. Cheers !
