Tried to create a new project today and got this:

I unstalled Unity 2020.3.17f, reinstalled it, and got the same problem.
Any ideas?

First thing I would try is force-close Unity, then open Packages/manifest.json with a text editor and get rid of all the default crapware that Unity installs.
Once that’s gone, blow away any Temp/ or Library/ directories within the project and reopen Unity.
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.
I’ll give that at try. Thanks.
