This is mine for fix for now, not a beauty but i can somehow work again:

The Distrobox AppImage Fix: Step-by-Step Guide

Important: Execute these commands in this exact order. Make sure you wait for your terminal prompt to change in Step 4 (indicating you are inside the container) before moving on to Step 5.

On the native host system (e.g., Kubuntu 26.04):

1. sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0
2. sudo apt update && sudo apt install distrobox podman
3. distrobox create -i ubuntu:24.04 -n orca-box
4. distrobox enter orca-box

Inside the container (orca-box):
5. sudo apt install fuse
6. sudo apt install libwebkit2gtk-4.1-0 libgtk-3-0 libgstreamer-gl1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-libav
7. sudo ldconfig
8. /home/username/Desktop/Snapmaker_Orca_Linux_AppImage_Ubuntu2404_V2.3.4.AppImage --appimage-extract-and-run
(Note: Replace username/Desktop with the actual path where the AppImage is located).
