MacOS Monterey et puce M1 max

The file looks good.

To follow your advice, I started by installing: bellsoft-jdk18.0.1+12-macos-aarch64,

You don’t want Java 18, you want Java 11. You don’t need jdk, you need JRE. And you need “full”, not the standard. Here is the link: https://download.bell-sw.com/java/11.0.15.1+2/bellsoft-jre11.0.15.1+2-macos-aarch64-full.dmg

without any result unfortunately

Did you run GanttProject from ZIP distro?
