Editor Crash When Compile Blueprint!

When I compile BP_GameInstance/GameMode, the editor must crash!!!

If I run the ue4 editor from visual studio, it appears as a exception!!!

I click “continue” in visual studio, but it stucks!!!

It’s a Really Really Really Serious problem!!!

This Is The Screen Shot When Crashing!!!

Finally, I figured it!
It’s because of I cast gamemode to bp_gamemode in bp_character.
