Launcher.LaunchFileAsync fails for opening a file extension associated with a desktop app

Question

I am trying using file association to open a desktop app from modern app. I followed all the steps correctly and am able to open the .try files with updater.exe through windows explorer. But when I try to do the same thing in my modern app programmatically, using

bool success = await Launcher.LaunchFileAsync(file);

I am getting the return value as false all the time. This works if I use DisplayApplicationPicker. What is going wrong here?

This is a know bug and there is no way for this to work if the user did not choose your app as least once. If you need inter-app communication, you can use "protocol association" which works every time.
