"The value of \"byteLength\" is out of range" error is thrown in the Hub logs



{"level":"error","message":"Unhandled promise rejection, reason: The value of \"byteLength\" is out of range. It must be >= 1 and <= 6. Received 8\n\tstack RangeError [ERR_OUT_OF_RANGE]: The value of \"byteLength\" is out of range. It must be >= 1 and <= 6.

Reproducible with: 2.2.0, 2.2.1

- The error often appears in the logs when the Hub throws "Unity is already in the list. You cannot locate the same version"
- The error also often appears when users are saying that for one or another reason they are unable to open the projects

use Command Prompt or Terminal to open Unity with command line argument -projectPath:
"<path to Unity.exe>" -projectPath "<path to the main project directory>"

    Hello, on August 10th 2020, I am using Unity Hub 2.3.2 and Unity 2019.3.15.f1 with a personal license and I confirm that the issue is still present.
    I have to open directly the scene of my projects as workaround.
    Maybe I can open a new bug ticket ?

    The fix for me was to re-enable the ethernet adapter. I'm on a laptop with separate Wifi and Ethernet adapters, but disabling Ethernet broke Unity hub despite it not being used at all (purely on Wifi). Re-enabling the Ethernet adapter fixed the issue. Reported as Case 1244367
