Steps to reproduce:

1. Create a new Universal 3D project.
2. Open Window > Package Manager > Universal RP.
3. Click "Samples" tab and click "Import" next to URP Package Samples.
4. You may have to change the Render Pipeline Asset according to the instructions in Game View.
5. Enter play and try moving in the following Sample Scenes:

*
** CameraStacking > MixedFOV
* Shaders > Lit

Expected results:* You can move.
Actual results: You cannot move. A message appears in the console stating that the FirstPersonController uses the legacy input system, and it needs set in Project settings. 

The movement will work once the user changes Project Settings > Player > Active Input Handling to Input Manager (Old) and restarts the project. However, this troubleshooting may not be known to a new user who might be exploring the samples.
