Repro steps: - make sure the hub is closed - open Unity 2019.2.0f1 directly (ie. run Hub/Editor/2019.2.0f1/Editor/Unity.exe) - The hub will open, but the project list will be empty. Closing the hub and then opening it normally (by running the hub app directly) fixes the issue. This is consistent for me. It's not a bad issue, but it means that there's something wrong in the "open the hub when opening Unity) behaviour.
