The game crashed when near a player who used a third-party 3D skin pack.

My game is crashed when other players use 3rd 3d skin pack like http://mcpedl.com/blokkit-skin-pack

I do know it is unsupported, but I don't think it is reasonable to crash my game, and it may destroy the multiplayer experience.

It happened in realms and LAN world. Maybe it can also affect the featured servers, but I don't want to be a "hacker"...

https://pastebin.com/gv8zM00m this dump is come from the MCMrARM's Linux launcher's output, it may be helpful for developer. (I use it just because it is hard to inject code to my OnePlus 3T, but I believe this problem has nothing to do with the launcher. It both happened in my phone and the Linux Launcher, so I try to use the stack dump file)
