    Glad you guys have found a remedy for this.

    I hope you are able backport the fix to the current "release" versions of Unity.

    Same thing here in 2020.1.2f1, except with this error:
    [PackageManager] Error Failed to parse response: Code 500 "The requested URL returned error: 500 Internal Server Error"
    UnityEditor.AsyncHTTPClient:Done(State, Int32)

    It's also not displaying any of my packages so I can't access them.
