I tried that and it didn't work, when I click the button my other hand doesn't disappear.

This should only happen if you have configured a Vive Tracker to instead of the hands, in the settings.
This may also happen if the game can't write the settings in its folder. For example if the game is in a folder managed by the system or over a network. You can try to move the game to another folder on your hard drive.
