Back navigation does not work after traversing the first page in a 10 page stack with Shell Navigation

[SoureMaster]

Description

I am currently using Shell Navigation on the app I am creating. There is a signup process in which the user must complete. Back arrow does not fire after traversing to the second page of a 10 page stack.

First Page - Landing page
Second Page - First page of sign up process (Back arrow works)
Third Page to 10th page of sign up, back arrow does not fire and the user is stuck.

I have added link to repository. Perhaps being new to Maui I am doing something wrong.

Hi @PureWeen @SoureMaster
This might be a little different with #24555
As for 24787, it does repro on Android and Windows, it is not a regression, and I found a similar issue here: stackoverflow 67653489
OUTPUT:
Open Page 2 then Open 3/4/5 pages and click back button:

[0:] Microsoft.Maui.Controls.Shell: Warning: Failed to Navigate Back
System.ArgumentException: Ambiguous routes matched for: //IMPL_PageOne/IMPL_PageOne/PageOne/PageTwo matches found: //IMPL_PageOne/IMPL_PageOne/PageOne/PageTwo,//IMPL_PageOne/IMPL_PageOne/PageOne/PageTwo (Parameter 'uri')
   at Microsoft.Maui.Controls.ShellUriHandler.GetNavigationRequest(Shell shell, Uri uri, Boolean enableRelativeShellRoutes, Boolean throwNavigationErrorAsException, ShellNavigationParameters shellNavigationParameters) in /_/src/Controls/src/Core/Shell/ShellUriHandler.cs:line 207

   at Microsoft.Maui.Controls.Platform.Compatibility.ShellToolbarTracker.OnNavigateBack() in /_/src/Controls/src/Core/Compatibility/Handlers/Shell/Android/ShellToolbarTracker.cs:line 228

So, I followed the workaround and just deleted "Route=" PageOne ""... then it worked:
