wixsharp: Confusing error: "API restriction: The assembly '' has already loaded from a different location. It cannot be loaded from a new location within the same appdomain."

After upgrade to 1.14.3, the error occurs. It is unclear whether the problem also occurs with 1.14.2

Logging the calls with first chance exception handler in place returns:

Striking is that the assembly is ‘’, instead of a name. Also peculiar is the NotSupportedException occuring from OriginalAssemblyFile enumerating FirstOrDefault().
