    Hi,
    in Unity Hub when I create a new project, and selected 2D or 3D and press [Create Project] , my cursor display the loading indicator for a few seconds, and then nothing would happen. No Unity splash screen, no active process in task manager for Unity Editor, nothing. only Unity Hub is working
    I tried clicking Unity.exe also doesn't work?
    I tried uninstall Unity Hub and Unity editor and Reinstall them and Same problem happens again?

    1. Make sure the GPU drivers and maybe intel chipset drivers are updated as much as possible. They're on the older side.
    2. Looking at the logs there might be a license issue. Maybe try removing and adding your license in unity hub

    Hi DevDunk

    before Unity Editor starts with no problem in my computer it happened after reinstall it

    The only way to start Unity Editor is to Disconnect from Internet then Click on my Project name in unity Hub and Unity Editor will starts normal
    it looks that windows Firewall or defender anti virus is blocking somehow Unity Editor but don't know how to Unblock it?
