I've been re-download Roblox Studio atleast 10+ times, I've even factory reset my computer. But for some reason, Roblox studio dosen't want to work the way it should, here is the error code I am getting all the time:
21:32:04.255 - Settings2 is not a valid member of Folder 21:32:04.255 - Script 'Script Context.StarterScript', Line 27 21:32:04.255 - Stack End 21:32:04.255 - Chat is not a valid member of Folder 21:32:04.256 - Script 'Script Context.StarterScript', Line 41 21:32:04.256 - Stack End 21:32:04.290 - PlayerlistModule is not a valid member of Folder 21:32:04.290 - Script 'Script Context.StarterScript', Line 42 21:32:04.290 - Stack End 21:32:04.291 - BackpackScript is not a valid member of Folder 21:32:04.291 - Script 'Script Context.StarterScript', Line 54 21:32:04.291 - Stack End 21:32:05.714 - TenFootInterface is not a valid member of Folder 21:32:05.714 - Script 'CoreGui.RobloxGui.CoreScripts/Topbar', Line 65

You probaly removed somethings important on your place, you need to re-make a new one.. If you didn't, uninstall Roblox,Roblox Studio from your computer by Control Panel>Uninstall a Program then re-download it by The website (www.roblox.com).
