Realms crashing upon trying to load.

I am the server owner for my realm. Earlier today i was playing on my realm with a friend. Then later when i tried to join the realm, it just crashed and took me back to my nintendo switch home screen. I have done everything. I have reinstalled the game and cleared my save data. I am still able to join other servers such as the hive, and also play with other people not on the server. The cause may have been upon trying to join a friend, it made me download extra behaviour and resource packs. Upon deleting them, it would delete, but next time i loaded the game it was still there. Even upon deleting my save data it would stay there. This may be either due to the server itself, or because of the function of deleting cached data and it not working properly.
