"Error: Could not find or load main class net.demilich.metastone.MetaStone"

When trying to open it on EndeavourOS (linux), I get the error

Error: Could not find or load main class net.demilich.metastone.MetaStone Caused by: java.lang.NoClassDefFoundError: javafx/application/Application
Anyone know how to fix it?

I solved this problem by uninstalling OpenJDK and installing java from the official website.
