everytime i join my friends world " I " crash it everyone else can join without a problem but its only me that crashes the world

This is unfortunately common. The way i fix it is by exiting the world (the host of the multiplayer game) and going back in. If this doesn't work, you could both reset your games.

Thank you for your report!
However, this issue is Invalid.

Crashes such as these are logged automatically, this will therefore be investigated further by the development team internally.
