unity hub wont open projects only create new one

when i try to open any old project unity wont open the editor only when i create new project it works kindly check the attached video

 

already tried solution like run as admin , create project on different hard disk not unity default location but nothing work today i will try to completely remove unity and reinstall also i will try the troubleshoot thread thanks

 

I'm having the same issue, driving me nuts, did you get anywhere?

 

Thanks for your support it worked after I checked the network tool and enable the disabled adapter i think yes its its license problem

 

This was the most insane problem I had since I started to use Unity. Thanks a lot @no4access . I've been working on this problem for the last 2 days. I tried

-Cloning the project from scratch on Git
-Cloning the project to a different folder
-Uninstalling&reinstalling Unity
-Upgrading Unity version of the project (this actually worked but, it wasn't the best for the project)
-Uninstalling&reinstalling Unity Hub
-Downgrading Unity Hub to an older version
-Uninstalling&reinstalling Git and GitHub Desktop
-Renewing my Unity license
-Trying to run programs as admin & Changing folders of installed programs
-Trying to open Unity with different environment variables

and yes the solution was enabling an ethernet connection that I don't use to connect to internet (I normally use wifi connection). WTF?!

Thanks again!
