Compiler errors with fresh install

I am a first time user and I have tried re-installing unity and I am still getting errors on a blank 2D project or a 2D platformer microgame. I have tried deleting the library folder and exiting unity as well as re-importing all assets. Does anyone have any idea how to possibly fix these errors?

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

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.
