Unable to launch any gtk+ applications

I was unable to launch any gtk+ apolications. when trying to gdb gtk-demo, got following error.

anyone can help?

Partial upgrade state?
Unsupported packages?

sudo pacman -Syu
pacman -Qs murrine
pacman -Qm

It looks like a WSL installation - which is only supported by your local system administrator.

it is a kde theme, which is like win11. I searched the error but no solution. Reinstalled it today.
