I was one among those having issues. Things have been working fine since I installed the QHY driver supplied by them. Here are my driver versions.
@Voyager You say: " QHY camera with internal filter wheel (the ones with the Final A code in the name) are declared not supported on Voyager if used with ASCOM driver directly inside Voyager." Is there a reason for this change? Do you know of another means by which it might be supported (I only ask since you say if used with ASCOM driver directly inside Voyager).
