It's a known issue fixed in the latest .NET MAUI workload.

1. Download + install the latest version of .NET: https://dotnet.microsoft.com/en-us/download

2. After updating to the latest version of .NET, open the a Terminal window and enter the following command:

• On macOS: sudo dotnet workload install maui;sudo dotnet workload update
• On Windows: dotnet workload install maui;dotnet workload update

This appears to be an issue caused by a mismatch between net9.0-android workload and the Microsoft.Maui.Controls NuGet Package.

For now, the workaround is to set options.SetShouldUseStatusBarBehaviorOnAndroidModalPage(false);

.UseMauiCommunityToolkit(static options =>
{
    options.SetShouldEnableSnackbarOnWindows(true);
    options.SetShouldUseStatusBarBehaviorOnAndroidModalPage(false);
})

@jfversluis Is this a known issue on the .NET MAUI team? It's nearly identical to the same issue that was resolved in SR3; here's the Discord link to our conversation about it.
