My project is using version 2018.2.21 of Unity, And everything was fine 2 days ago.
But for some reason, today, Unity Hub refuses to open my project with Unity 2018.2.21.
As you can see, I have the right version installed, and it matches the version of my project.
But when I launch it :

(I click no)

I have tried launching it outside the hub by opening Unity 2018.2.2 independently, but apparently it still goes through the hub because the Hub gets launched, and unity just doesn’t open.
I’ve tried to force open the project by opening a scene directly from the project’s folders, but the same thing happens exactly as when I launch my project from the hub.
I’m using the last version of the Hub. I have also tried re-installing it.
This is blocking me from doing anything and I’m getting seriously tired of this…
