Good news for anyone finding this post. I found a solution. In Xcode I went into Signing & Capabilities for the app and removed my Apple ID then put it back in again and clicked the Download Manual Profiles button and removed the app from my iPhone, then rebooted the phone. When I tried to verify the app again everything worked. Apple really needs to fix that bug.

As an update to my post, I found out that DJ Pro AI from Algoriddim has been updated to work with Ventura. Unfortunately, Pioneer told me not to upgrade because they didn't yet test for my particular controller. Has anyone out there tested it on their DJ Pioneer controller with Ventura. I really want to upgrade.

I do, but it's not supported since it's a 2015 MacBook Pro. Looks like I will have to wait because both companies also told me to wait until they do testing.

Yes, I did ask both Pioneer and Algoriddim and both companies told me they have not done any development or testing of their software and drivers on Ventura.
