Roblox bug?

I have a problem: I get this error message when I try to start Roblox

I have restarted the laptop 2 times but I keep getting this error message. I've already tried to uninstall and reinstall Roblox (don't know if I did it right) and I get this error message again.

What should I do?

So I don't quite know because I only have Roblox on my mobile phone, but this message says that an important setting could not be used correctly or that it could not be downloaded, try uninstalling and installing it
