To stop UI navigation in Roblox, press the Escape (Esc) key on your PC to open settings.
Next, navigate to the Help section and preview your current keybindings. Look under Miscellaneous for the key that toggles UI Selection or UI Navigation. By default, this is the backslash () key.
Once you have identified the key, press it to toggle UI navigation ON or OFF. This will disable the UI navigation and prevent it from interfering with your gameplay.
This simple method helps you regain control over your Roblox experience, ensuring smooth and uninterrupted gameplay.
