Can't launch the appimage verion nor install the rpm package on Mageia 9

[amuhz]

My friends asked me to install some mods on Lethal Company but i've encountered 2 problems installing r2modman :

Firstly, i've downloded the rpm package and tried to install it, but then a popup telled me that i'm missing some gtk3 package, if i relaunch the process multiple times in a row, it says that i'm also missing libXtst and liuuid. I've tried to install them with my package manager, but it continue to says they are missing.

In second time, i've tried to install the appimage version, because normally it works on most distribution and i've already some software where i use their appimage version. But when i launch it, it opens a a window and crash a second later, if i launch it with the terminal, it says that gpu process was not usable.

I'm on a laptop running with an intel iris Xe for integrated gpu, nvidia RTX 3050 for discrete gpu and i'm using Mageia 9.
Here the software specification :

• KDE plasma version : 5.27.5
• KDE Framework version : 5.105.0
• Qt version : 5.15.7
• Kernel version : 6.5.13-desktop-6.mga9 (64-bit)
• Graphics Platform : X11
