Crash is in native capacitor library due to missing hasOwn property on core JS object. From reviewing hasOwn - it looks like this was added to IOS around 15.4 - so suspect user has out of date OS that is incompatible.
Advised they upgrade at least to 15.8 (latest IOS-15 patch) or upgrade to a much more recent IOS-17 if their phone is capable.
User has older iPhone 8 with IOS 15.3.1
