It is not even a house corner, but the side wall. But the problem exists at all windows and at one house corner even a few small spots in the upper corner without a window.

Maybe the cold wind is hitting it just right.

Windows have nothing to do with the corners (only indirectly through ventilation). It rather sounds like you have a fundamental issue. Whether it is due to you (not enough heating, not enough ventilation) or the building fabric must be examined by a specialist on site.

30-year-old plastic windows also have poor insulation values, and if the seals have never been replaced and the fittings haven't been readjusted, then they are simply no longer properly sealed. Condensation forms quickly. This all looks more like a fundamental building fabric problem and can hardly be solved by ventilation or tighter windows.

Had the house been left empty for a long time? Apart from the explanation already given here about cold bridges at the corner of the timber frame, the mold on ALL the windows does not quite make sense to me – in an inhabited and reasonably heated house by usual standards.

The house, or rather, the apartment was never empty. It was always heated but often also ventilated with the windows tilted.
Who is typically consulted to inspect and assess this?
Thanks to everyone for the input so far!
