Crash with SwiftUI(0x0 ???) that happen only on M1 iOS app since a few weeks
Hi,  I have a gnarly crash that I don't understand how to fix. The issue is actually on the AppStore version of the app when I click on "Discover pro feature" button it should open a modal but instead it crashes. This app is an iPad app that works on a Mac M1 machine and crashes only in this configuration(don't crash on iPhone or iPad). From my understanding the crash seems to be coming from SwiftUI. I can only reproduce it on the store version on the dev version(freshly build) it does not crash. Do you have any ideas to have a way to reproduce it? Maybe the ips file gives some insight into what is happening.  2022-06-13-112851.ips.txt Thanks for your support, Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000000 Exception Codes: 0x0000000000000001, 0x0000000000000000 VM Region Info: 0 is not in any region.
