Yes, I was getting this munmap_chunk(): invalid pointer error and after LD_PRELOAD trick i get this one about qt.plugin.
But reinstalling libxcb-xinerama0 worked fine !!
Thank you

In my case this fix is not working:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
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, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.
