Forum:Game End Crash

Please help me!

I am on my first playthrough and am at the Vault. Whenever I fight and kill the Destroyer my game crashes. Right when it dies (I think it's when it dies, it could just be when it gets really really low health) my game just closes. When I come back in he's still there with full health. There's no credits or cut scene just whenever I shoot the last bullet BL disappears.

Please please help.
