Hey! I'm the one who asked on reddit a couple weeks ago for this linux version. Works great when launched from the executable, but not using the launch.sh script. :) I run arch linux.
Try downloading it again. :)
I have recompiled the tool on an older version of Ubuntu and I removed some system libraries from the lib64 directory.
I have tested it on Ubuntu 16.04, 18.04 and Arch Linux and it works from the launch.sh script. ;)
