I’m attempting to create a Flatpak from the Python-based Amulet Minecraft Map Editor. The Flatpak building is fine, and the app launches without an issue, but when loading a saved Minecraft world in the 3D editor, I get this:

It looks to me like there was some issue with wxPython creating the 3D map canvas, but I’ll be honest here - I have no idea what all this means, or even where to begin when trying to fix it.
So I figured I would do the same thing that the Flatpak builder does, and install Amulet with PIP. Well, that’s when I get this other error:

I’ve been to the application developer who sent me to Flatpak, and the Flatpak people said I should talk to Python, and now I’m here because somebody at Python said it’s not them, it’s you.
So, can somebody help me understand what’s going here? The Flatpak version of the app actually runs just fine, until you load the 3D canvas for the Minecraft world. Then it crashes. Running the base application generates an instantly fatal error right out of the box and doesn’t even load the GUI.
