iOS App Not Compiling Correctly, Opens Directly To Garbled Menu

This one has me stuck. I’m trying to export a Creator project that up until today had exported fine. When I did an update to my project after having been away from it for a while, I re-exported as normal and uploaded with Xcode. What shows up on my phone, however, is completely wrong.

This is how the app is supposed to look, per the Creator simulator:

This is how it looks on my device, an iPhone 7 Plus:

As you can see, the app opens (after the splash page) on the menu, with all of the text stacked on top of itself on one character and the tabs completely jacked up.

My default page is set to “Welcome”, the front page in the simulator example.

I have tried reloading old builds of the app, and they are loading fine. The differences between builds have been minor, just removal/replacement of certain content.

Any help someone could offer would be greatly appreciated. I don’t want to have to scrap this project and restart from scratch.
