Thanks.

The full crash report makes it clear that you’ve hit an assert within UIViewController. Sadly, I’m not a UIKit expert and that makes it hard to say exactly which specific assert you’re hitting. If no one else chimes in, I recommend that you open a DTS tech support incident and discuss this with one of our UIKit specialists.

Hi @JL_W were you able to resolve this, we have the exact same crashes and the only one's left in one of our app. Any help will be deeply appreciated. Thanks
