Issue on iOS but not web: "Exception thrown while executing UI block"

Please provide the following:

  1. SDK Version: 40.0.0
  2. Platforms(Android/iOS/web/all): iOS. Issue does not occur on Web.

I get the following error only on iOS, not on Web. According to my log message output, all React components render but still this error message is thrown and when I dismiss it, the screen is all black.

Since the error message does not really state any React component or function, I’m at my wit’s end here.
I tried a debugging session but even with “Pause on exceptions” it does not stop and point to a code line.

Can anyone provide a clue which component might be the culprit?
As stated above, the app runs perfectly fine on the Web platform.

you should downgrade your react-native-svg (.eg 9.3.x)
