Narrator says "Operation Timed Out"

I have a WPF application with a couple of custom UI Elements that can be invoked. One shows a System.Windows.MessageBox, the other shows a context menu.

When I press enter to execute them using Narrator, it announces "operation timed out" instead of the right contents. The strangest part is that this does not reproduce when I click the elements.

Any ideas on why Narrator would say such thing? How can I investigate this further?

Hi,@ JullyanaMattosVycas-8292.
Which Narrator are you using? Is it a screen reader for win10 system? For further analysis, please show your detailed steps and related complete code.

I'm using Narrator for Windows 11 Enterprise:

Edition Windows 11 Enterprise
Version 21H2
Installed on ‎30/‎06/‎2021
OS build 22000.194
Experience Windows Feature Experience Pack 1000.22000.194.0

I'm from the Visual Studio team. I can't share the code broadly, but feel free to reach out to me internally.

Some thoughts:

If I replace my custom button with a standard WPF button, the dialog is announced. However, if I replace it with a standard WPF Hyperlink, the bug reproduces.

Narrator focus indicator does not leave the hyperlink when the bug is reproduced. If I press enter again, Narrator says "command not available" even if keyboard focus should be inside the dialog.

I was able to reproduce with other elements that "steal" focus, e.g. context menus.

Again, feel free to contact me for more info.
