Game crashes

Hi.

Since last night (05/19/2019), my game crashes when i load a saved game.  Started a new game and seems to work but my previous keeps crashing.

I play solo and don't have multiplayer mode on.  Saved game is about 189 MG and save directly on the Switch (no memory card).  I was working on my 4th map and was just about to complete exploring it before this happens.

I have not done anything or built anything special.  I was exploring many maps to find all the mats i can find.  Been playing this in survival mode using the natural skin pack.

Please as i have spent many hours in this game don't feel like starting all over again.

Thanks!
