Fix bug where apps cannot be launched on iOS 18

[HRCJ7]

Closes #42

I reviewed the details of the previous issue ticket, which was marked as resolved with version 4.0.1, specifically mentioning that the issue was fixed for iOS 18. However, after updating to version 4.0.1, I can still reproduce the same issue on iOS 18.
