Stopped working – Solitaire Review

I have enjoyed playing this game for a very long time. For some unknown reason it has stopped working . I am using an iPhone 12 Pro with version 14.3. All I get is a black screen that does not clear and must be closed down. I was at level 247. Is this a reported problem? I hope that there is a fix for this.
