Unreal Engine 5.10 Enhance input doesn't Work with HTC VIVE Controllers

[s.bien]

What worked for me:

1. Disabling the proximity sensor as @Rectus_SA said,
2. In your Unreal project, go to Plugins → Turn on OpenXR and turn OFF SteamVR.
   This fixed the controller inputs, and now all the buttons are working as expected.
