Server is crashing constantly

Hey everyone,
sometimes the server is crashing. It only happens when some players are online. I don't think. that this is relevant for the GitHub-Issues. So I'm posting it here.

Here is the crashdump:

Maybe someone could help me.

 

Upload crashdump here https://crash.pmmp.io/

 

"You got an error! I'm a teapot." -> if I try sending my crashdump.

 

Tried again, but the same error occurs while uploading the file.

 

What I think: The world is corrupted. The meta of a block is wrong.

 

Same as I thought before. :/ Is there some kind of way to fix it, without generating a new world and deleting the "old one"?

 

I will say something but I do not know if it will work. Backup the world first. Convert it to anvil using a converter (search on google). If it is already an anvil world do not do that. Then put the new world (if you did not convert, put the old one) to your PC. Put it to the saves folder in .minecraft and open Minecraft Java. Hop into the world and break the torch. Then save and quit Minecraft java and put the new world in the pe server. Hope you understand.

Good luck!
