Performance issues with Switch version

So...
• Everytime a world passes 45Mb on Nintendo Switch version, it start to lag hard.
• Blocks instead of break just turn invisible and eventually drop.
• Sometimes the day doesnt change to night and vice versa.
• Eating food eventually restore your hungry but then the food reapears on the inventory and the hunger counter return to the past value.
• Characters are freezing on multiplayer split screen mode.
• Mobs are freezing or teleporting on split screen mode.

• You cant lace mobs because the character is lagged and they dont follow you properly making the rope break.

Note: Those issues just start to happen after the world reach 45Mb or more.

A world just increasae its file size brutally if I go explore new places and its ruining the experience. I have to create new worlds to play because after the world reach a certain file size it turn impossible to play.

Im using the graphics on the minimum with no effects and its effecting even solo player or multiplayer
