I’ve got very similar messages too. Just upgraded to PostProcessing Stack v2.22 from v2.17 or so. Unity version 2018.3.8f1.
If I do modifications to my code and come back to the editor, I’ll get these errors again and the Post Processing is disabled on the Game tab. Either clicking play or scene tab and back kinda resolves it. Hopefully it doesn’t cause any problems further down the ine.
Having the same issue: Cinemachine 2.2.9 + Unity 2018.4.5f1

Don’t know why previous versions are no more available through the package manager. Manually changed to 2.1.7 in PackageManager/Manifest.json and downgraded properly. No more annoying error stack.
No, you can only install version 2.2.2 at least on my version 2019.3.0f3. But it’s maybe possible to bypass by changing the version in the package manifest, which feels like an unnecessary hacky workaround to me. I’m just going to wait for 2.2.3
I’m having the same issue with 2019.0f3, when I double click on the error it brings me to my camera game object which has a post-processing stack layer on it. Hope it’s fixed in version 2.2.3, otherwise, I’ll have to test my game by exporting it each time. When I press the play button, the editor completely freezes and I have to end the process in the task manager.
I’ve been having the same issue, everytime i press play i get a bunch of errors that when i click them they highlight my camera, and the only fix is removing the post processing layer, but i need it for the post processing volume to work. I’ve updated the post processing stack v2 in the package manager from 2.2.2 to 2.3.0, by clicking the dropdown arrow to the left of the package, and still i get the same errors. What should i do? I don’t have any extra windows, and i’ve previously utilized HDRP, LWRP and URP, but ultimately went back to the builtin pipeline, and i’ve already unistalled those packages from my project but now i’m getting these errors i didn’t get before so maybe there’s some residue left or something.
