Hello, thank you for making a bug report!

I believe this is a result of an issue described in #14 in this comment specifically. I've been working on it recently and I think it is due to the dependencies not being bundled with the AppImage.

This was a little difficult to implement since not all Linux distributions have libadwaita >= 1.8.0 in their official package repositories, but it is definitely possible to do so by bundling the dependencies on a more cutting-edge distro such as Arch Linux.

I pushed some changes in the build/bundle-appimage-dependencies branch that could hopefully resolve this issue. It is still undergoing a lot of testing, so it will likely take a couple of days or weeks for it to actually be merged.

It should now work for x86_64 devices using the AppImage under the latest commit to main. ARM devices will not be supported for now due to GitHub Actions' container limitations. I'll keep this issue open until it is resolved for aarch64 as well.
