World crashes when creating and created ones are corrupted

Just like the title says, when trying to enter world just says it's corrupted, whenever creating a new one it's says saving world for a few seconds and then crashes, tried regenerating, didn't work
I'm not sure if it's because of my wifi problems at that time, but it wasn't that awful that I couldn't do anything and after it got fixed it's still happening! Not a single elements in my workspace are broken and there are no errors either, it just broke for no reason!
Please help :(



Edit: I figured that it might have been structure that I made, I deleted it, but it still error! Please somebody help! I don't wanna loose my workspace I worked so hard on it!
