White dots on windows

"Hello, I have a problem with white spots appearing on the windows. At first, they appear as small dots that the Denoiser removes (it's set to 3000 iterations), but by 5000 iterations, spots start to appear—first one, then it grows larger, and by the end of the rendering, two more spots suddenly appear."

I've attached the files: before Denoiser, after Denoiser (3000 iterations) at 5000 iterations, and what I get in the end.

    Probably reflections of the light source - so not literally noise. It takes time to appear because it needs to be fairly direct paths from light to glass to camera, which are rarer than glancing paths, though the final dots may be reflections of reflections.
