### What happened?

App is acting as if dialog box/modal has not been dismissed. As a result the app is useless.

Edition Windows 11 Enterprise
Version 23H2
Installed on ‎11/‎29/‎2024
OS build 22631.7219
Experience Windows Feature Experience Pack 1000.22700.1108.0

### Steps to reproduce

Asked it to Create a canvas for me, which it did. I noticed that some of the features in the HTML needed to be fixed so I asked it to fix it. From there a Copilot Desktop Dialog box let me know that the work was finished. X out of the box and the app still thinks that there is a dialog box. No matter if I kill the process its acting as if the alert has not been dismissed. If I restart, same issue.

### Expected behavior

Not to act like a dialog is there when there is no dialog.

Reproduisez ce problème sur Windows 11 avec la version 1.0.9 en créant un canvas, en demandant de corriger son HTML, en fermant la boîte de dialogue Copilot Desktop et en redémarrant l’application. Aucun fichier ni point d’entrée n’est indiqué ; le travail est considéré comme terminé lorsque l’application ne se comporte plus comme si la boîte de dialogue était toujours ouverte après sa fermeture, l’arrêt du processus ou le redémarrage de l’application.
