Legend of Zelda Windwaker emulator crash!

[Berserking5]

Hello guys, ive got a problem unfortunately.
My emulator is crashing after playing Windwaker for about 20-30 mins, im using a very new dev. build.
The dev. build is the version 4.0-5285-x64.
i set the emulator to Open gl, cause when i switch it to direct3d i got a very low framerate.

Hopefully someone can help.

Thanks

Does the crash shows any messages? If so, post a screenshot of it here. Make sure you don´t have any cheats in the game (they sometimes make the emulator crash).

actually i cant make a screenshot of it, the whole emulation monitor gets black, and in front of it this message shows up(in german):

[Window Title]
Dolphin.exe

[Main Instruction]
Dolphin.exe funktioniert nicht mehr
