I tried it 2 ways, first was via Xcode second was via TestFlight (I have an apple approved build there) and in both I see the crash. I tried your suggestion and tried it both with Xcode 13.3 and 13.4 as well and I still see the same issue. Unfortunately like you pointed out, I'm not sure if I can downgrade tvOS nor do I have a spare device pointing to an older version. The weird part is, the app is approved for release in the app store and I did not even touch the storyboard(the app has been in the store for some years now). So makes me wonder if the tvOS version is the problem. The app has multiple storyboards and other ones load fine, only this one seems to be the problem. All the storyboards are loaded in the same manner and are in the correct location as expected !
