Can't launch Krosmaster on Arch Linux.

I can't launch Krosmaster Arena on Arch. After the very first update it won't start updater at all with following error messages:

qt.qpa.gl: Choosing xcb gl-integration based on following priority
 ("xcb_glx", "xcb_egl")
qt.qpa.gl: Xcb GLX gl-integration created
qt.qpa.gl: Xcb GLX gl-integration successfully initialized
libGL error: unable to load driver: r600_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: r600
libGL error: unable to load driver: r600_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: r600
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

PS: I've dealed with such errors earlier, which were caused by outdated libc++.so libraries (in MATLAB ) but trying to delete such file in "transition" directory does nothing because file returns after restarting Krosmaster.

PS (2): Also tried to change LD_LIBRARY_PATH in startup script adding /usr/lib to use system libraries but it results in segfault.
