FilePicker on MacCatalyst app is not working (occasionally)

Description

FilePicker returns null as soon as it pops up, 8 out of 10 times. var result = await FilePicker.Default.PickAsync();

Steps to Reproduce

1. Create a new .Net MAUI App on Mac in Visual Studio.
2. In the MainPage.xaml.cs add the following (to the sample button handler OnCounterClicked:

var result = await FilePicker.Default.PickAsync();
if (result != null)
{
    int u = 0;  
}

1. Put a breakpoint on the “if” statement and run the app.
2. Click on the button on the sample app.

This should let you choose a file and the name should return in the result above. But instead it sometime just returns with the result null as soon as the dialog pops up.

If you don’t see the bug, try to restart the app, or rebuild it.
