Even though the issue may originate with Roblox, the majority of the reasons listed below are related to your game files and other applications that can disturb the game's critical functions.

For the most part Roblox works pretty well, but sometimes you get errors like ‘Failed to Download or Apply Critical Settings.’ Figuring out the problem is a bit of a head-scratcher.

In reality, there is no Roblox error code that tells users to call 911 because someone else is nearby. “Error code 1001” does not seem to exist on the platform at all.
