Black screen on the newest 1.21 beta when the deferred rendering is enabled

When I turn on the deferred rendering on the newest 1.21 beta the screen goes black(1st picture)but when I turn on deferred rendering on the beta 1.20(3rd picture)there's no problem🙁

 

I tried to turn it on with another pack and I think the problem is the fog, because if I turn it on the a black glitch will suddenly appear(2nd picture)

 

I know this is the 2nd time I've reported, but thank you for reading this
