Failure to open – Blackjack 21 + Free Casino-style Blackjack game Review

Had this app on my phone for years and this is the best blackjack. The last I phone update has prevented me from opening the app. I even deleted it and reinstalled. Every time I attempt to open it automatically closes. I really hate it. Need help.
