Why does Roblox crash with an “Unexpected Error”?

Roblox may crash with an error message saying that it is an “roblox unexpected error” due to game files becoming corrupt, the video card drivers, there may be conflicts with other software, or not enough memory space left on the PC. When System admin makes changes to antivirus or firewall settings and other background applications also hinder. To solve the problem, you should try to update your system, close programs which are not in use, and reinstall the Roblox application.
