Cheat commands in zombies render my game unplayable

[Flow425]

I wanted to test something out on mob of the dead so I wanted to give myself guns and god mode to get there quickly. Godmode worked just fine but when I tried to give myself a weapon, it appeared but it also turned my screen black and white with a wavy filter that almost looked like zombie blood. When it did that I was unable to gain points anymore and I was also unable to end the game, the yes button just straight up didn't work. I looked up this issue and couldn't find anything about it.

Use a script or a mod menu, this command is bugged
