Hi, i have 3 systems, all AMD and all Asus MB's. Roblox works on 2 system without any issue but on one system its getting crashed as you said without any reason. In my case i have installed roblox from Microsoft Store, so what i did...
- Uninstall the game.
- Update Microsoft Store
- Open Edge, go to roblox website, login and install it from there. It will download a small exe then install the complete game.
- It will create a shortcut on the desktop, right click -> Properties -> Compatibility and check Run as Administrator.
- Run the game, it will prompt for some message, press yes and see if its hanging anymore.
For me, when i was installing the game from Microsoft store, its hangining, when i installed the game from roblox website and run it as admin, it was not hanging untill today. So i can that the frequency of hanging roblox is reduced.
Give it a try.
Regards,
Ariz
