Stuck in Generating terrain screen in a realm

Just created tge account to know a possible solution.

Well I was building, everything normal and got a lag problem, I couldn't open my inventory so I waited a sec then tried again and then I could access to the blocks, placed some of them and then I got disconnected. 

Tried to log again but the "generating terrain" loading screen was starting to take a while, closed the game and tried again it kept the same. I tried mostly everything even deleted the application and it didn't worked. I thought it was a total fail and tried to log to another realm; and everythingwas fine. Is there a way to solve this? Because of these i couldn't be in my minecrafty-wedding.
