I don't seem to have any issue using Unity 2022.3, so please make sure that you :
- Install the Input System and Cinemachine package (To install a package from Unity go to Window -> Package Manager -> Search for the name of the package and install the plugin (if you can't find it in the results make sure that you set the list of packages to display the content of Unity registry at the top left of the window))
- Make sure your project uses the new Input System package (Edit -> Project Settings -> Player -> Other Settings -> Active Input handling -> Input System Package (new)
and restart the editor afterward, if you still face some issues try to re-import the plugin after that, if even after that it still doen't work, feel free to tell me
