The first and easiest thing you should try is a restart of your PC. Many players are able to launch Roblox after they restart their computers, so it's definitely worth trying. If rebooting your PC doesn't solve your problem, try the next fix.
Go to Settings on your phone and look for Time Settings. Since Roblox operates in different time zones, you need to make sure that your phone has an accurate date turned on. Otherwise, you'll be experiencing crashes continuously in different applications, so you better watch out!
