Octave Not Working

I Installed Octave Flatpak, on Linux Mint 20.1 cinamon. It installs without any warning, but it does not run.

I Installed VLC Flatpak, that works fine.

I did a new install of Mint 20.1 cinamon, and installed Octave Flatpak again, installs without any warning, but still does not run.

Is it broke, or is there something I’m missing ?

Thanks

Octave 6.2 (Flatpak) on Linux Mint is now working. New build with fix released through Flathub.

The problem was not all x86_64 CPU types were being supported.
