Missing 32 bit mesa drivers or incompatible GPU with unsupported prime-run / bumblebee,
only nvidia-prime is known to work flawless with optimus

[KingTheGuy]

as far as i can tell, i do have the 32bit mesa drivers, also using nvidia-prime.

nvidia prime != prime-run/bumblebee
You need to reinstall it correctly, nvidia prime doesn't allow gpu switching while running the desktop (you need to login / logout with it)
Your error has nothing to do with this launcher at all

@KingTheGuy I found a workaround/fix (at least one that works in my case).

Here it is.

This is how to apply it:
In Arch Linux case, after cloning mcpelauncher-linux-git.git and cding into mcpelauncher-linux-git you must makepkg -os, then cd src/mcpelauncher-manifest, apply the patch as below, cd back into mcpelauncher-linux-git (cd ../..), makepkg -e and continue as normal.
In Debian & Solus cases, you must apply the patch after cloning mcpelauncher-manifest.git and cding into mcpelauncher-manifest (or mcpelauncher if you strictly follow instructions from README), after applying continue as normal.

wget https://gist.githubusercontent.com/kanafutile/d77b5b89ff2c2aa32c77fa57e12bfc1f/raw/e7a2e06ee7eb56ca9b5649a880e509051f63ea10/eglut_from_mesa_demos.patch
patch eglut/src/eglut.c eglut_from_mesa_demos.patch

P.S. Running it in nvidia-only mode (the one that has PRIME Synchronization) works well without this patch.
P.P.S. New nvidia drivers might be a requirement, because I only tested this on Beta NVIDIA drivers. 32-bit libglvnd and 32-bit nvidia-utils might also be required.
