This project uses an extremely outdated version of Cinemachine, from the asset store, that we no longer support. Please use the following steps to upgrade Cinemachine to a supported version:
Delete the "Cinemachine" directory from the Assets folder
Open the package manager
Install Cinemachine version 2.9.7 or later
Use the GameObject menu to create a default Cinemachine Virtual Camera.
The console will no longer log error messages.
