Loading screens when I open a chest all my inventory randomly

Randomly when playing it will come up with a loading screen when I open a chest or my inventory and then take forever to load normally cancelling out the game and forcing me to restart in using Nintendo switch and it happens in realms and single player I play relms more offen the single so I notice it more in realms

Also invisibility Potions don't seem to work on Guardians they can still see me without any armour or holding any tools they still kill me in both realms and single on the switch bedrock
