Thank you @sal_vager. I've added the player.log. I hope this will be enough...

So, I've downloaded ksp this morning. It started up normally. Then I created a new sandbox save. but after some minutes it was still loading. I forced quit ksp and I restarted it. So i tryed to do a carrier save and science save, but the game was still loading for a minute and then the game seems to block. Then i've tried to play some scenarios or training but it was the same. Could someone help me?
