RNSVGSvgView drawRect crashes on iPhone 12 Pro with iOS 14.2.1

[uripre]

Hello beloved maintainers 🙏

I received a crash report from one of my users with an iPhone 12 Pro. The app crashes for him every time he opens the app, but allegedly he managed to open it once at the beginning, but not since. After partially symbolicating the crash report, I was able to see it seems to be related with react-native-svg based on the RNSVGxxxx classes, here is the stack trace I have:

It doesn't reproduce on any of the other devices I tested it on (but my app still has only a few users so this is the only iPhone 12 Pro that attempted to use it), and it doesn't reproduce on a simulator with an identical spec.

I wasn't able to reproduce this crash locally 😞 Any ideas how to further investigate or any ideas why this might happen?

I can confirm the app doesn't crash once I remove react-native-svg and the SVG files from the app.

Hello @uripre, @Daha62,
If the issue still persists, could you share an example and the steps to reproduce it?
Thank you.
