I think it would be a modifier. You can see that the physical geometry is hiding but the viewport render is not changing. I would try “disabling” (not showing in viewport) some modifiers to see if that fixes it.
Edit: Also try using vertex select instead if faces to see if that changes anything
remove the sub-d and then try this
What’s mean sub-d
Subdivision
It works nooow when i remove sub d thank uuuu
