Unity Editor opens and closes due to failed license check

Hi. I'm using Unity Editor 2020.3.33f1 LTS. When I launch a project, the splash screen opens and closes a few seconds later with no error message. I checked the logs at

AppData\Local\Unity\Editor\Editor.txt

and here's what it says (at [name] it references my user account name, so I've censored that):

The license is well before expiry and was just created. I've literally uninstalled every Editor version I have, uninstalled Unity Hub and then reinstalled everything again. That let me launch the app once, then I had to restart it (I changed the input system) and then it failed to start again.

I've tried everything I can, could someone tell me what I need to do for it to not fail the license check? I've attached an image of the Licenses page.

 

Pretty sure licensing issues won't be solved in a public form. I suggest opening a support ticket with Unity.
