Hey! Actually I had the same problem and I tried to make both the procedures for "Game cannot be opened" and “App is damaged and can’t be opened. You should move it to the Trash”, but unfortunately the problem persists, I also tried to install the file a pair of times but it makes no difference :(
I deleted my other comment to say that I ended up figuring it out! all I did was download both versions (bought the full blessing and public ones) and just launched the one I wanted to play and...it...worked? don't ask why it worked, but it did lool may not be the solution for someone else but that's how it opened/played for me!
