I have an in house application that I develop for my company. The application requires our corporate MDM profile is installed on the phone. I recently got a new phone and our corporate IT team installed the MDM profile and the Comp Portal application for me to manage our corporate applications.
I installed the application through the Comp Portal. It crashes right away when I launch the application and I see this error message in the Console when connected to the phone: "SpringBoard Snapshot generation request for bundleID: com.mycompany.mygroup.appName rejected due to the app being denylisted."
I see other errors from runningboardd about failing to spawn the job and SpringBoard Bootstrapping failed for <FBApplicationProcess: 0x510affd80; app<com.mycompany.mygroup.appName>:<invalid>> with error: <NSError: 0x301e60090; domain: RBSRequestErrorDomain; code: 5; "Launch failed.">
I can launch a development version of the application with no problem by connecting the USB cable from my machine to my device and running through XCode.
Other people have no problems launching the application. I compared all the certificates in the management profile with another device where the application does not crash and there are identical.
We checked a number of settings on the devices to see if there could be something preventing the application from running but found nothing.
We reset all settings and deleted and reinstalled the application with rebooting to see if perhaps it was an incomplete installation. Our IT folks want to wipe the phone and start over but I have little confidence that will fix the issue since we don't know the root cause.
I am concerned that one of my Stakeholders might have the same issue if they get a new device. This application worked fine on my old phone.
Device: iPhone 16 Pro Max iOS version: 18.2.1
Any ideas on next steps to troubleshoot this issue? How can I figure out the cause of the denylisting?
