The type or namespace name 'Plastic' does not exist in namespace 'Unity'

How do I completely remove Plastic and collaboration from my project. I turned off the version control (I use git and bitbucket), however it still seems to haunt the project. If I install the Newtonsoft.Json through NuGet, it still reference the one in Plastic. I change the references in the project, yet unity still breaks the references. It seems to be impossible to get rid of it, and keeps erroring things out since it cannot the reference right. It’s very invasive, yet causes compilation to fail. Using 2021.3.22f1.

Extra unwanted packages in new projects (collab, testing, rider and other junk):

Temp/UnityEngine.TestRunner.dll Error

Recent versions of unity have an annoying habit of crapping useless packages into your project. When those packages inevitably have errors, this sort of thing happens. I have railed about it before. Go into the package manager and remove crap you don’t need, like the entire test runner and collab and whatnot. If you feel brave you can hand-edit the Packages/manifest.json file a lot faster than using the laggy package manager interface that only lets you remove one package at a time: [7287748-…

About the fastest way I have found to make a project and avoid all this noise is to create the project, then as soon as you see the files appear, FORCE-STOP (hard-kill) Unity (with the Activity Manager or Task Manager), then go hand-edit the Packages/manifest.json file as outlined in the above post, then reopen Unity.

Sometimes the package system gets borked from all this unnecessary churn and requires the package cache to be cleared:

Unity3D Package Cache errors(?)

Thanks for your response after I removed the mentioned packages and added “com.unity.nuget.newtonsoft-json”: “3.1.0” to the manifest it finally work, though Unity did crash, however after it came back up all errors were cleared out.
