Looks like a big part of the developers is having the same problem (even me), let’s wait until Roblox fix it. Don’t worry, we might be able to develop again.
The first time i saw this happen i was using team create, when i tested in a new baseplate it still crashed. So activating/deactivating team create doesn’t solve it sadly.
Experiences have to be published for team create to even be available, or else there would be no way for other people to join. So no, they don’t come enabled.
What these guys said appears to be working for me as well:
So for whoever is having this problem, every time you open a project, click RUN instead of PLAY a few times and it should fix the crashing momentarily until you reopen studio.
Clicking Run always work, but we also need to test the game scripts, as example of us, LuaU programmers, we will need to test the game with play everytime.
