I recently upgraded to Xcode version 15.4, but after the upgrade, my app stopped working. I resolved all the dependency issues and managed to run it locally. However, when I archive and distribute the app, it shows a blank white screen upon launching it on the phone. Any troubleshooting suggestions would be greatly appreciated.

I need help! It is an enterprise IOS application. After installing the new Apple distribution certificate in my keychain and redeploying the application, testing devices are encountering an error message stating " needs to be updated. The developer of this app needs to update the app to make it work for the new version of iOS". if the "Keep" button is clicked, the app is still functioning.  Background: The previous deployment was in July 2022, and there was no issue. Only after I update the distribution certificate, this error occurs. The application was archived using Xcode 11.7. I know XCode 11.7 is old, but there were no issues before. The previous deployment in July 2022 was using 11.7 as well. I am not sure whether this issue is caused by the new distribution certificate or the out-dated Xcode 11.7.
