After upgrading the iOS system to 18.3.1, the APP crashed continuously when it was launched. The following log was seen in the device log： Bootstrapping failed for <FBApplicationProcess: 0x72ad16b80; app<com.xxxx.yyyy>:> with error: <NSError: 0x300cd4d80; domain: RBSRequestErrorDomain; code: 5; "Launch failed."> { NSUnderlyingError = <NSError: 0x300cd4ab0; domain: NSPOSIXErrorDomain; code: 85> { NSLocalizedDescription = Launchd job spawn failed; }; } Our APP is in-house distribution What are the possible causes? How can I solve it?
