On first click the share sheet shows nothing

I am developing an application as a project for training. This is a meme sharing application. I use .sheet in order to present a modal view to share meme given as an image :

.sheet(isPresented: $showingSharePage) {
            ShareSheet(items: items)
        }

Here is my code for the share sheet :

struct ShareSheet: UIViewControllerRepresentable {
    var items: [Any]
    
    func makeUIViewController(context: Context) -> UIActivityViewController {
        let controller = UIActivityViewController(activityItems: items, applicationActivities: nil)
        return controller
    }
    
    func updateUIViewController(_ uiViewController: UIActivityViewController, context: Context) {
        
    }
}

Here is my share button's code :

ToolbarItemGroup {
                    AnimatedActionButton(title: "Share", systemImage: "square.and.arrow.up") {
                        items.removeAll()
                        let snapshot = meme.snapshot()
                        items.append(snapshot)
                        showingSharePage = true
                    }
                }

The problem is that when I open for the first time (when application is launched), it doesn't show anything :

After after launching once, it works alright.

Why is it doing this ?

P.S : For further information, I share the whole GitHub project (this is a project for a course from Udacity) : https://github.com/m4thus4n/Project
