I had the same problem, I could only solve it by removing the -Objc flag from Other Linker Flags, which some cocoapods packages insert because it depends on libs .a, this flag causes it to import unused codes that cause this error to happen, with me the problem is with Google Mobile Ads that inserts this flag, but the curious thing is that this problem only happens with iOS devices that have iOS versions below 18.4, the iPhone 15 with 18.4 the problem does not happen, now with all devices with 18.3, 18.2 and even 15.2 the application does not open.

Now the million dollar question, is the problem with Xcode or with third party libs that still depend on the -Objc flag?
