Crash on startup ( could not load needed library **libgnustl_shared.so**)

[c2vi]

I am using the x86_64.Appimage from ChristopherHX.

I am using Ubuntu 18.04.4 LTS. The Launcher works, i can play old versions like 1.5.3, but 1.12.1.1 and 1.14.60.5 for example do not work.

I found out, that all versions work, besides 1.12.1.1 and 1.14.60. I removed those two versions and reinstalled them, then it worked. Those two versions were not downloaded with this Appimage which I was using to play them.

If you want to use the newest versiones of Minecraft I recommend this Fork of the launcher. It worked twice for me, but was very hard to setup.
