installer-downloader/src/controller.rs line 66 at r1 (raw file):

    let Some(architecture) = get_arch().ok().flatten() else {
        // Could not retrieve the host's CPU architecture for whatever reason
        delegate.queue_main(|self_| {

Could the error handling be moved into AppController::initialize? By passing in something like architecture: impl FnOnce() -> io::Result<VersionArchitecture>.

This should be gated behind windows || macos.

We could either use modal_fatal_message or display this error before creating the AppWindow at all. Currently, the MessageBox dialog doesn't prevent the main window from being focused.
