Hello, thanks for your reply!
Please check your SteamVR status. If your controller icons are greyed out, you may not be able to use your controllers. Please make sure your controller icons are in color mode.
What's more, we noticed that if you haven't done SteamVR Room-Setup, your controllers may not work. Please check out the link to launch SteamVR on your PC, and run Room Setup.
We'll keep looking into the problem.
