So I found this reply in another one of the topics
And that bug is because scripting is enabled, 700 objects created and no scripts being run.
There are two ways to avoid that bug:
1 If you aren't using python at all but uncheck "enable scripting"
2 Just run a script every frame. It doesn't even have to do anything, a comment will work.
I bet this is what's going on with my crash. Going to test it when I get home.
