[🐛 Bug]: WindowHandles: some Edge browser URLs causing timeout error

[Pique7]

What happened?

Suddenly (obviously after recent MS Windows update) I get a timeout error when I try to access WindowHandles after creating a new tab and navigating to one of those Edge browser URLs:

edge://apps/
edge://browser-essentials/
edge://downloads/
edge://favorites/
edge://history/all

This error might also occur with other URLs, but I only had problems with these Edge browser URLs.

This happened with MS Edge v133.0.3065.59 for the first time (see exampe .NET/C# code to reproduce).

How can we reproduce the issue?

EdgeDriver edge = new();
edge.SwitchTo().NewWindow(OpenQA.Selenium.WindowType.Tab);
edge.Url = "edge://favorites";
System.Diagnostics.Debug.WriteLine(edge.WindowHandles.ElementAt(0));   // Timeout error after 60 seconds.

Relevant log output
