    Unity is not even opening for the current project.

    Also this may happen if you accidentally forgot to remove the part of your code and set it into a infinite loops of 'for loops' them calculating and spawning gameObjects (in-game). Serious "Oops!" as some might say.
    (25 + 25) * infinite = enough objects to crash unity and give you this issue.

    This may happen if you Instantiate a prefab on Awake which in turn instantiates another copy of itself recursively.
