Greetings!
This is Tin, I got this issue too before, and what I did is reinstall the Roblox app from Roblox website, to do that, go to https://www.roblox.com/download and download the exe file by clicking Download Windows App. Then install the it to your PC. Please make sure to uninstall the current app first.
Please let me know how it goes.
Thanks,
Tin
