Black font for desktop icons since update

Hi, I actually dont know since when, but it is just a couple of days ago when the font on my desktop symbols switched the color from white to black. I havent fiddled around with any of my settings for many months.

I have the default (white/light) appearance. I dont use dark mode. I use Orchis as shell-theme.

Does anybody have any idea what to do to get the light/white font on the symbols back?

Many thanks!
