Can not Add new projects to Unity Hub, I select the folder but nothing happens??

Can not Add new projects to Unity Hub, I select the folder but nothing happens??
I have uninstalled Unity Hub, and reinstalled it.
I have installed and used projects before, but now I have a new project version to add and cannot add it.

Any help would be much appreciated
Sincerely,
Blaine

Not sure if you uninstalled and reinstalled it trying to fix the problem but that might have caused the problem.

I just came across the same problem and for me I was not able to add a project as my first project after a fresh installation. Creating any new project fixed this issue and allowed me to add existing projects.

This is most probably a bug though.

Workaround was to create new project, then add old project, lastly remove newly created project.
