Cinemachine doesn't work for me in Unity version 2021.3 and I have no idea why

Here’s an Image of the errors I’m having if anyone can help

This is an error in that release of Cinemachine: it didn’t account for the possible removal of the Timeline package. There are 2 solutions:

  1. install the Timeline package, or
  2. Upgrade to a newer version of Cinemachine

Thanks for answering but there are still errors even with both imported
If you can, please let me know where to find the correct ones if these are the wrong ones

Edit: Nevermind, if anyone else has this problem, all you gotta do is remove the timeline package that’s pre-installed in the package manager if you’re using Cinemachine 2.8.x
Go to Window > Package Manager > Unity Registry > Timeline > Remove
