Looping on Aptio Setup Utility, can’t access Windows

I was playing a game, BitBurner, and left the computer running for like five minutes without touching it. The game was in a stable state, I was not testing scripts or doing anything he didn’t handle before.
But when my eyes came back to it after the 5 minutes, the game had frozen. Couldn’t click on anything ingame, right clicking on the icon in the tool-bar froze the whole thing, so I turned it off by pushing the power button.
Now it loops on the Aptio Setup Utility, and I don’t know what to do.
I don’t care about loosing all datas, even if I’d like to avoid this option.
What can I do ?
