I right click on a folder and see its info. I try to analyze it with Filelight.

It doesnt matter if the folder is through symlinks or not, its the same effect.

qt.qpa.wayland: setGrabPopup called with a parent, QtWaylandClient::QWaylandXdgSurface(0x55657095e660) which does not match the current topmost grabbing popup, QtWaylandClient::QWaylandXdgSurface(0x556570f1da60) According to the xdg-shell protocol, this is not allowed. The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly because xdg-shell mandate that child popups close before parents
kf.kio.widgets: Could not find mount point for QUrl("file:///home/user/some/directory")
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
QString::arg: 2 argument(s) missing in org.kde.filelight
F: Not sharing "/usr/share/icons" with sandbox: Path "/usr" is reserved by Flatpak
Error: Invalid fd passed

This is the output I get. Filelight is not opening. Launching it normally and opening that folder works.
