Issue description

I downloaded the Godot Character Controller project from GameDev.tv and imported it into my Godot project list. Whenever I open the project for editing in the Godot editor, my PC immediately starts lagging for a few seconds, and then it freezes completely. I can't move the mouse or even do a Ctrl+Alt+Del. I just have to power off my PC and then turn it back on.

Steps to reproduce

Note that these steps may crash your PC, so be careful!!
Download the Godot Character Controller project. (I will try to attach it below)
Unzip the project.
Open the Godot Project Manager window and "Import" the project.
Click on "Edit" to open the project for editing.
Within several seconds, your PC should freeze.
