- [x] I have read the "Reporting a bug" section on Contributing file: https://github.com/CommunityToolkit/Maui/blob/main/CONTRIBUTING.md#reporting-a-bug

### Current Behavior

Application crashes with PlatformView cannot be null here when drawing view is used inside bindable layout. app crashes while changing the item source of the bindable layout. This happens on both Android and iOS.

Error Started after upgrading to Microsoft.Maui.Controls 8.0.60+ (latest release 8.0.92 also has same problem.)

Please find Git repo that produces same error:
https://github.com/mahesh139/MAUIBugs

This was working fine with **Microsoft.Maui.Controls 8.0.40**

### Expected Behavior

Changing bindable layout item source that contains drawing view must not crash.

### Steps To Reproduce

1. Open and run the solution.
2. Click on "Section 2" button, this will change bindable layout item source (no items in source)
3. Click on "Section 1" button, App crashes with PlatformView cannot be null here error while changing item source.
