It seems like the GetAwaiter().GetResult() call is not waiting for the task to complete. I am not sure if this is a bug in the Coyote package. I have also tried using the Coyote package with a .NET Framework 4.8 console application. The code also does not wait for the task to complete. The output is as follows:
