try restarting the game. if you are using ps controller, make sur to use DS4 windows

In the settings, is gamepad enabled?

I believe I found the issue, I had installed hd textures for some zombies map and placed them in the main folder. when I removed them, then the maps loaded properly. Thanks for the help!

It gives error "Needed to allocate atleast 16.0 mb to load images". Anyone else have the same?
