[WIN10] Unity seems to be stuck at start

Hello peoples of the forum~

So today, I decided to jump into the world of unity and try to make some fun game to practice and learn.
Although, When i Open the software it seems to be stuck on a white screen with a loading bar that never stops.

I made a tiny video of it that you can find Riiiight here : https://twitter.com/AEgwinn/status/919971217729359872

Do any of you guys have a solution ? Waiting for your answer, I'll continue to scarvenge the internet seeking for one.

Good day to you ~
