pureBDcraft Swtich water black

[TinyyNoodle]

when i try to swim in water everything goes black and it wont go back to normal unless i get out of the water and it wont let me save my game
it doesn’t happen with any of my other texture packs
(i am playing on the switch)

The only fix to this I'm aware of is restarting the game.
