I don’t know if this is just me or something. But almost everytime i try to open another place on studio while I already have one open, it crashes. Well to be more specific i get the spinning wheel of death and i have to force quit, or it just upright crashes. I am on a mac aswell. I’m not sure if this is just a me thing or an actual bug.
There is a fix going out for macs next week I believe (Ben posted this elsewhere)
This might fix the issue you’re having.
You should also mention in your post title that you’re on mac. “Studio crash bug” isn’t really useful at a glance 
Could it be related to this? Every time I open a place / go into play solo (regardless of whether one is currently open or not), Studio freezes for ~20 seconds before continuing like normal.
@Echo
No. I only get a studio crash/freeze if I edit another game will I am editing a different game.
But who knows…
