    Hi.

    I just updated windows 10 to version 1803. When rebooting it asked me for permission to use my location, permission to use my advertising id etc. And I said no to every one of them.

    When starting Unity HUB it prompted me for a serial and when I inserted it It gives me "serial failed to validate - empty hwid from client". My guess is that I have now revoked the possibility for programs to access my advertising identifier and the unity serial thing is dependant on that.

    I feel like I have been spending more time struggling more with the unity serial in this program than I have actually saved by using it. Why does this tool need me to sign in or ask for a serial? Its two jobs is to open the correct unity version for a project (which requires a separate unity serial window) and install unity versions (which should not require a serial).

    I opened my unity project the old way by locating the correct unity exe file and opening my project. The next time I wanted to open Unity HUB it worked without me having to enter my serial again. So it somehow found out I had a valid serial again.

    Also happened to me both on Windows 10 and macOS. Only managed to make it work again by launching Unity manually.

    I'm stuck behind this bug, too. Here are my repro steps:

    1. Logged into Unity Hub.
    2. Entered my serial number. A small label appeared beneath the text field noting that my serial number was valid.
    3. Pressed the "next" button.
    4. The entire window flashed white and returned me to the same serial entry field screen, but this time the breadcrumb UI at the top of the window was missing.
    5. Removed and re-entered my serial number. It was verified a second time.
    6. Pressed the "next" button. Nothing happened. Pressed "next" many more times without a response.
    7. Relaunched Hub.
    8. Entered my serial number. I was presented with the error mentioned in the original post.
    9. Logged out of Hub.
    10. Looped back to step #1. The same issue occurs 100% of the time.
