Bug New Editors don't get installed through Unity Hub

Trying to install the 2019.3.0f 6 Editor through Unity Hub 2.2.2
- It completes the installation bar, but then disappears from the Unity Hub UI.
- Relaunching Unity Hub shows the Editor in the installs tab, but it is in the constant "Installing" status.
- The "2019.3.0f6" folder was created, but is empty.

The issue already exists here: https://issuetracker.unity3d.com/issues/new-editor-versions-dont-get-installed-through-hub, and has been stated as "Fixed", but I can't seem to actually find the comment that fixes it? Unless the "fix" is installing the editor manually instead of through Unity Hub, which is very undesirable

Installing the editor manually is way too painful because I also need a bunch of extential modules like the android JPK and SDK, which is handled much easier through the hub.

I have changed the security of the installation folder so that everyone has permission to use it, and I've also tried to change the installation folder to somewhere else. But the same problem happens. When the hub has finished installing the editor, a folder appears at the installation path, but it's empty. The editor in the hub UI disappears, until you relaunch the hub (but not completely quitting it as it warns about a an editor currently installing when you do), then the editor reappears in the UI, but is in a constant installation mode where the blue bar just loads forever.

These are my most recent installation logs:
