Are Playstore app updates tested before release?

I've been playing Solitaire Klondike ad free on my Xiaomi Redmi Note 10 for almost 3 years. It's an old app and there have been no updates until today, when one came through (for compatibility with Android 13 IIRC). I've been on 13 for some time, but thought it might be worth updating the app in case other changes had been made. So against my better judgement I installed the update.
On running, it locked the phone up with a green screen (the app background colour - baize green), instead of advancing to the card layout. Even when working with the previous version the app hadn't, by design, shown the system buttons at the bottom of the screen. In the end I had to reboot the phone to get back control. I uninstalled and reinstalled the app and tried again with the same result. I did find that after several attempts swiping up on the green screen would show the system buttons for a few seconds, and I could get back to the phone's main screen. I've uninstalled the app.
I can't believe that this update was properly tested before release, unless for some reason it's only my phone it doesn't like.
