because your computer might need to update the game, i suggest using task manager to shut down studio and open it up again, it will save everything
Since you didn't explain your answer fully, I'd assume it's an issue from your computer. Basically, the reason it may not work is that you have files that slow your computer down; delete any files you don't need, I suggest going through task manager and deleting it!
If this didn't help you, try reinstalling ROBLOX! This way your computer will keep up to date with the newest version.
This then again maybe a ROBLOX issue.
It's a Roblox issue. It always happens to me. Try waiting until the output says "an auto recovery file was created" until closing it with task manager.
