I believe there are issues at multiple points. The following solves the issue which stalls the initial launch and gives the “Access is denied” errors which would otherwise have required three “Cancel” button clicks and a closure of the empty black box.
There are three TGZ files at “C:\Program Files\Unity\Editor\Data\Resources\Packages”. These three files need to be unzipped to become TAR files, and then again unzipped to each become “package” folders. These package folders need to be renamed according to the name of the original TGZ file:
unityeditor-cloud-hub
unityeditor-collab-toolbar
unity-editor-home
At the location of “C:\Users%user_name%\AppData\Roaming\Unity\Packages” create a new folder named “node_modules”, and put the three unzipped folders inside. The TAR files should still remain and now that they have been unzipped they serve no purpose. They should be deleted. The TGZ files may remain as backups.
I got this solution from Lertmind .
The Unity Package Manager Error stated above remains unresolved.
