Strong fogging of the windscreen

Hello together, I have a now 2 year old Kia Ceed (Kombi) EZ 03/2021. I bought it in December 2021 with 130km as a daily registration. I am also really satisfied with the car. But there is a pitfall: The windshield strikes strongly and freezes from the inside in winter. The spare wheel pit is dry and I can not detect any moisture in the footrooms. Today the car was in the sun for at least 5 hours at my work. It was like this. The questions are: Did one of you have the same problem and could possibly solve it? Would that be a case for the guarantee? – In my opinion yes. Thank you. Best regards Raphael
