Crash on Inspector during play

I'm getting this crash any time I run the game, pause, and go to select one specific object in the Scene Hierarchy, it crashes immediately before anything has even shown up in Inspector. This object is the only object in the scene running a script, and it is a moderately sized script, but I don't know why the Inspector would be the thing crashing it.

Any idea how or why this is happening?

The scene has no models or textures.
