Today I found that some Cinemachine componet(CienmachineImpulseSource) attached to gameobjects before are becoming missing after I switch project to Unity2002.2.0b4.

Also I can’t find and add component in Inspector.

although I can find the script in project package folder.

I created a new project and tested, there’s no problem add these components.
I tested remove and reimport cinemachine package and the problem can’t be sovled.
How can I solve this problem?

OK, I delete the line of cinemachine info in package manifest and redownload then the problem is sovled.

I found more package script become “missing” state. InputAction of InputSystem can’t be edit, and some of my purchesed assets produce error too. These packages works fine in a new created project. And no matter what I do I just can’t get them loaded correctly.
