[SOLVED] OBS Studio cannot open on KDE wayland

DE: KDE+wayland

I've just updated the system and then I cannot open obs studio.
The error log:

$ obs
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vkkhrdisplay, vnc, xcb.
