how to install minecraft on Cachyos ??
paru minecraft-launcher
choose 1 (the official one)
Il you want to choose another launcher:
paru minecraft
Choose between many launchers
or the old school way:
git clone https://aur.archlinux.org/minecraft-launcher.git
cd minecraft-launcher
makepkg -si
use Prism launcher 
CachyOS Package Installer > Repo > prismlauncher
+1 for prism launcher, so much less of a headache than the official launcher (assuming you’re only interested in minecraft java, not bedrock edititon)
I use mcpelauncher. Welcome to Minecraft Bedrock Launcher’s documentation! — Minecraft Bedrock Launcher documentation
Android version
Real especially if you wanna use A custom Jre Version Or Mod the Game.
