This problem started, I think, after I started to use DataStore (DataStore2).
Currently, every time I set a breakpoint and start debugging, when I stop the game in Studio, it freezes for 30 seconds and then I get this error:
Not running script because past shutdown deadline (x8)
- Open the project (sent via DM to https://devforum.roblox.com/g/bug-files - https://devforum.roblox.com/t/project-file-log-about-studio-bug/713985)
- Open StarterGui -> LocalScript
- Set a breakpoint in some line (for example 444)
- Play (F5)
- After the program pauses at the breakpoint, stop the game
Here you might have the same symptom, ie, Studio freezes for 30 seconds and then shows that error message.
