I tried starting the release desktop jar like java -jar FeudalTactics-desktop.jar on an arm64 Ubuntu Touch Linux device, but keep getting:

I assume, it is requiring OpenGL support, while Ubuntu Touch provides GLES. As you support Android, I assume that GLES should be supported by this game. Is that correct? Can you provide any guidance how to package/start the game so that it utilizes GLES?

I think you might need to edit the config in de.sesu8642.feudaltactics.lwjgl3.Lwjgl3Launcher. See https://libgdx.com/wiki/graphics/opengl-es-support.
