Create src/Core/AndroidNative/maui/src/main/java/com/microsoft/maui/MauiAppCompatActivity.java with contents:
• Locate the `dispatchTouchEvent(MotionEvent event)` method within the `MauiAppCompatActivity.java` file. The exact line numbers (X and Y) are placeholders as the full file content is not provided in the snippets. The method is mentioned in the issue description but not shown in the snippets.
• Inside the `dispatchTouchEvent` method, before any operations are performed on the view (or views) that are intended to handle the touch event, add a null check to ensure that the view is not null. If the view is null, the method should return `false` to indicate that the touch event was not handled.
• The modification should look something like this: ```java @Override public boolean dispatchTouchEvent(MotionEvent event) { if (event == null || findViewById(event.getSource()) == null) { return false; } return super.dispatchTouchEvent(event); } ```
• Note: The `findViewById(event.getSource())` is a placeholder for the actual logic used to retrieve the view from the event source. This needs to be replaced with the actual method or property access that is used in `MauiAppCompatActivity` to get the view that would handle the event. The key point is to check that this view is not null before proceeding.
• This modification ensures that if the view intended to handle the touch event is null, the method safely returns `false`, preventing the `NullPointerException` from occurring.

Description
And stack shows: MauiAppCompatActivity.dispatchTouchEvent MauiAppCompatActivity.java, line 57 Haven't searched the maui code, but maybe it's possible to check if the view still exists before calling/dispatching touchEvent.
