macOS 15.1 MFMailComposeViewController.canSendMail() returns false always

In my Catalyst app I use

func setupMailComposer() {
        // Check if the device can send email
        guard MFMailComposeViewController.canSendMail() else {
            print("Mail services are not available")
            showMailErrorAlert()
            return
        }
        
        // Create and configure the mail composer
        let mailComposeVC = MFMailComposeViewController()
        mailComposeVC.mailComposeDelegate = self
        
        // Set the email details
        mailComposeVC.setToRecipients(["example@example.com"])
        mailComposeVC.setSubject("Subject for your email")
        mailComposeVC.setMessageBody("This is the body of the email.", isHTML: false)
        
        // Attach a file (optional)
        if let filePath = Bundle.main.path(forResource: "example", ofType: "pdf"),
           let fileData = try? Data(contentsOf: URL(fileURLWithPath: filePath)) {
            mailComposeVC.addAttachmentData(fileData, mimeType: "application/pdf", fileName: "example.pdf")
        }
        
        // Present the mail composer
        self.present(mailComposeVC, animated: true, completion: nil)
    }

Since I have updated to macOS 15.1 the canSendMail() function returns false although I have configured Apple Mail (like before in 15.0 where it worked flawlessly).
