Computer freezes when playing in editor after creating a new blueprint

Are there any logs in your project directory’s Saved/Logs subdirectory?

The title sums it up. After creating a blueprint and playing in editor, the viewport turns black and then my whole computer freezes after a few seconds and I have to do a hardware reset or power my computer off. The editor works perfectly fine otherwise. I have turned off blueprint compiling when playing in editor but it makes no difference either way.
