Game Crash when I join My Server

I Have almost 10 days that i cant join my own server because it crash the game.

I play on Nintendo Switch, a realm for 2 players, I am the owner.

I was playing with no problems since I add Grapling hooks and paleocraft addons. I tried removing them from the realm but the problem continues. 

The loading bar and the music stops rigth there.

Then the game crashes and prompts "the game has closed due to a error".
