Licensing Client fails to launch when opening Unity Hub

-

Reproduction steps:

1. Open the Unity Hub
2. Observe the Unity Hub

Expected result: Unity Hub opens
Actual result: Unity Hub fails to open

Reproducible with: 1.16.2

Reproducible on: Windows 10, Windows 11, macOS 24.0.0 (M1), macOS 24.1.0 (M1), macOS 24.2.0 (M4 Max), macOS 21.6.0 (Intel i5 1,6 GHz), macOS 23.2.0 (Intel i3 3.6 GHz)

Notes:

-Not reproducible by CQA
-All versions listed under "Reproducible on" were reported by users
-For this exact scenario the following error lines should be present: {{Process exited with code null}}, {{Failed to launch licensing client: Error: Timeout}}, {{Failed to start Unity Hub, reason: LICENSING_CLIENT_CONNECTION_ERROR: Failed to establish a connection with the Licensing Client}}
-A potential workaround involves performing a clean reinstallation of Unity Hub by first backing up the editors-v2.json file. Then, delete all files located in Users/[username]/Library/Application Support/UnityHub (for macOS users) or C:\Users\[username]\AppData\Roaming\UnityHub (for Windows users). Afterward, reinstall Unity Hub and restore the editors-v2.json file to its original location

  1. Resolution Note:

    This should be fixed with the new start up improvement for the client v1.17

    The workaround says to do the following:
    Uninstall Unity Hub
    Open “C:\Users%username%\AppData\Roaming\UnityHub”
    Backup “editors-v2.json” file (information about installed Editors is kept here)
    Delete all of the files inside
    Install Hub again. You can download the latest Hub installer from “https://unity.com/download
    Open “C:\Users%username%\AppData\Roaming\UnityHub” and paste the saved “editors-v2.json” file here.

    But there is no editors-v2.json file in the folder. I also can't open any Unity Editors directly either so this is blocking all Unity development for my business.
