Application crashes with unhandled exception when navigating between pages using button click in .NET MAUI (.NET 8 and .NET 9)

[aruljenithberkmans]

Description

We are experiencing an issue in our .NET MAUI application when navigating from a main page to a listview page using a button click and then returning back to the main page. If this action is performed recursively, the application sometimes crashes with an unhandled exception.

In button click, use the Navigation.PushAsync method to navigate the second page.

Steps to Reproduce

1. Create a .NET MAUI project with two pages:
   a. Main Page: Contains a single button.
   b. Second Page: Contains a simple ListView control with some data.
2. On the Main Page, set up the button click action to navigate to the Second Page.
3. On the Second Page, provide a way to return to the Main Page (e.g., using a return arrow or back button).
4. Navigate from the Main Page to the Second Page by clicking the button, then return to the Main Page.
5. Repeat steps 4 multiple times.
6. Observe that after several iterations, the application crashes with an unhandled exception.

Expected Behavior:

The application should allow continuous navigation between pages without crashing, regardless of the number of times the action is performed.

Actual Behavior:

After repeatedly navigating between the Main Page and the Second Page, the application crashes with an unhandled exception.
