The window is simply too poorly insulated and therefore too cold on the inside. Either a new window, or wipe it with a towel in the morning. We currently live in the [DG] and do this every morning, it's not that much effort.
For me, tilted/open windows etc. would also not be a solution. People are different. Ventilation is the easiest. It is enough to simply move the air in the room so that the moisture can escape.
