GTA not working properly?

So I recently got myself a laptop with which I'm currently writing this text. Anyway, I bought Gta 5 today. After it had finally finished installing after 5 to 6 hours of downloading, I started the game. (I bought the game via the Rockstar Games Launcher.) When I started it it was just as if I had clicked on this minimization window. So what everything that is currently reading on the PC have in the top right. So one to the right of the cross. In any case, it's just very small and the GTA expansion is blocked by the game for me. Does anyone know what's the problem? Or did any of you have that too? Or does someone know what I can do now to get the full screen on gta again? (I hope that I explained it well)

I don't have the game in mind now, but you should deactivate the window mode in the settings of the game and set the correct resolution!

Window mode sounds right
