Unreal Match 3 black screen on startup

Unreal Match 3 was downloaded from the App Store. It gives me a black screen after startup and stays in there until I force quit.
Was observed on both the iPhone XR (14.0.1) and iPad Pro Gen 3 (14.0.1)

Interestingly, it runs on my wife’s iPhone X (13.6)

Seems to be an incompatibility issue with 14.XX iOS
