Takes good picture, but a lot of bugs – CamWow Retro: Vintage photo booth effects live on camera! Review

I love this camera app. I've had it for 5 years now, but just recently it started to do this weird problem. I'll open the app and the camera will be nothing but blackness and when I try to flip the camera the app just closes down completely. I've tried resetting it and I've tried uninstalling and reinstalling it, but it's still doing it. Please fix the app.
