Unity won't open when wireless adapter is disabled in Windows Device Manager although internet is coming from wired connection



How to reproduce:
1. Open Windows Device Manager
2. In the network adapters tab select Wireless Adapter and disable it
3. Open the attached project ""

Expected result: project opens normally or shows some kind of error
Actual result: project does not open

Reproducible with: 2019.3.9f1, 2018.4.20f1, 2017.4.39f1
Not reproducible with: 2020.2.0a5, 2020.1.0b4

Note: creating a new project opens it, but once closed it will not open again. Also, newly created project launches in Unity with personal license, part of the log file is below:

    Not fixed! Submitted another bug about this. My onboard Wi-Fi has failed. I cannot open Unity. I have tried reinstalling multiple times multiple versions. Cleared every trace of Unity and re-installed from scratch somehow not having Wi-Fi means Unity doesn't open. Even though I have a perfectly fine wired connection to my router.

    I have the opposite problem, Unity Hub 2.3.2 and Unity 2019.4.1f1 - Wireless connection is internet connection, wired connection is an internal network - when wired connection is disabled in Windows, Unity won't load a project...

    This error is still happening on Unity Hub 2.3.1.
    If WIFI adapter is disabled but wired connection is enabled, Unity editor doesn't start.
    But when I turned on WIFI adapter enabled, Unity editor runs well.
