I can’t replicate the issue, and libraries and packing pipeline is not something I can edit; still, for those who face issues with v1.2, try this v1.3 build that is based not on nw.js but electron. Hopefully, it will help.
Hm, that’s a different error reported by Terracottafrog at Discord, I missed that point. Those were the libs bundled with ct.js, but your error is more about another shared library that is supposed to be installed.
Try sudo apt-get install libnss3, or something else depending on your distro. Google should help with other possibly missing libraries.
