webkit2gtk appears to not be installed, install it using sudo apt install libwebkit2gtk-4.0-37 and it should be solved.

Its a pretty odd requirement for an appimage to require a specifically versioned system library like this. The whole point of appimages is you include enough libraries in them to NOT be so dependent in system libraries that change between OS releases.

In any case, it looks like this was done by design @Botspot and we should be changing to a new release name which includes these libraries. See here for details https://github.com/davidk/PrusaSlicer-ARM.AppImage/releases/tag/version_2.9.1 . The old release name isn't even available anymore in the latest version, which is why the auto updater hasn't been pulling it in. If all our supported systems work with the new release https://github.com/davidk/PrusaSlicer-ARM.AppImage/releases/download/version_2.9.2/PrusaSlicer-2.9.2-aarch64-full.AppImage we should switch over to it.

This should be fixed now with the newer appimages that include more system libraries.
