I have a project that I develop with my friend. However, anytime I try to playtest the main game it crashes as soon as I load into a playtest. The last thing I did was add a hinge to a part and it suddenly began crashing. I have since removed the part and still crashing.
Some things I’ve tried:
Reinstalling
Reverting the game to an earlier (known good) version.
Trying on a different computer.
Disabling scripts (on both the client and server)
Some things to note:
Sub-places work fine.
The game ALSO crashes using the Roblox client. (not studio)
I wonder if your Mac can’t run big projects. Check your Activity Monitor on your Mac when you open it up and see how hard it runs. Also did your project work on a different device?
I also wonder maybe there is a virus in your game from using free models.
