I installed Arcolinux with Hyprland successfully on my Intel NUC. What should i say - it´s absolute aweseome, so smooth and clean

The installation is up-to-date. Installed it yesterday. There is an error for the Archlinux Tweak Tool.
Here is a screenshot

Normally i would create an issue on Github. But since i'm complete new to wayland i don´t know if it is a general wayland GTK error or not.
Can someone confirm that ?
Thanks for your help!
