Unity freezes when I play or run

Basically, if I press play in the editor to test the game (or build and run), Unity freezes (or I get a black screen when I play from the .exe) and maybe about 20 seconds to 1 minute later, it crashes. I don’t have any canvas in my scene and I’ve checked for infinite loops. Please help, I’ve looked everywhere and I’ve found some similar problems but never the same as mine and the solutions never work.

My map is a tonne of cubes and the scale of them is quite large and a terrain with a couple of trees, not sure if it’s just an issue with the rendering or something. I use Unity 4.6 on Windows 7.

try disabling all of the objects in the scene and play with only one object enabled at a time… :confused: hope it helps
