After updating to 21.2.3 DialogService is not working correctly

I use the Dialog Service through our application. I noticed yesterday after I updated to 21.2.3, it is no longer working.

The isConfirm value never comes back.

bool isConfirm = await DialogService.ConfirmAsync("Do you want to delete this date and all of its services?", "Delete Date"); ToastService.ShowInfo(isConfirm.ToString());

if (!isConfirm)

Have confirmed that when I roll back to 21.1.41 the DialogService is working correctly.

In my case:

bool confirmResult = false;

//--> dialog window opens

confirmResult = await DialogService.ConfirmAsync("Are you sure?", "Confirmation",

                      new DialogOptions()


                         PrimaryButtonOptions = new DialogButtonOptions { Content = "Yes" },

                         CancelButtonOptions = new DialogButtonOptions { Content = "Cancel" },


//--> "await" does not stop until the window is closed

//--> the window is visible, but the execution of the program does not wait,

//--> confirmResult is false, regardless of the dialog result

if (confirmResult)




In version 20.4..0.53 the DialogService is working correctly.
