Same issue and bug related on gitlab.xfce.org: https://gitlab.xfce.org/xfce/xfce4-settings/-/issues/222
My laptop with Xfce 4.16 on Xubuntu 21.04.
I've rebuild xfce4-settings without the support to upower-glib and now the bug disappear.
On xfce4-settings 4.15.3 the upower-glib is disabled by default: https://gitlab.xfce.org/xfce/xfce4-settings/-/tags/xfce4-settings-4.15.3
