Xcode AX problem Bug with Siri Extension only occurs on physical device

Question

I have an application that's using a Siri extension, and I am having issues when the user attempts to add their own custom voice shortcut. This issue can only be reproduced on a physical device and doesn't appear when I run the app on the Simulator.

Immediately after the user taps the "Add to Siri", the code in the below IBAction handler executes:

//ViewController.swift

@IBAction func didTapAddToSiriBtn(_ sender: Any) {
                guard let shortcut = INShortcut(intent: ShowCommandIntent()) else{return}
                let addShortCutVC = INUIAddVoiceShortcutViewController(shortcut: shortcut)
                addShortCutVC.delegate = self
                DispatchQueue.main.async {
                    self.present(addShortCutVC,animated: true,completion: nil)
                }

After the self.present() runs, it causes the following message to be output to the console:
[AXRuntimeCommon] Unknown client: {MY_APP_NAME}

Then, the user adds their custom shortcut to Siri, and the following stack trace prints in the console (3 times, shown only once for brevity):

I've tried restarting both computer and the test device and cleaning the build folder but with no success. What could be the issue here? I know a lot of other Extensions have had this issue.

Any help is appreciated.
