Can you also report the bug to Qt and glibc? No KDE code is in the backtrace.
Are you using accent color from wallpaper?

Git commit 3c2437815920856608a27361fe1da03e763742a5 by Fushan Wen. Committed on 04/10/2022 at 15:41. Pushed by fusionfuture into branch 'master'. kded: properly delete factory to fix file descriptor leak Not unloading the plugin loader will cause file descriptor leaks in kded, and when fd limit is reached, accent color can't be updated anymore because updating accent color requires writing to kdeglobals. This fixes the leak and also fixes the accent color bug.
