Programming & Scripting

Hi I’ve been developing an app and have done well over 40 builds which have installed and ran fine. Today I made some UI changes, mostly cosmetic, and now it hangs at the splash screen and force closes. The issue is, it doesn’t give me any errors in the log except one which only happens at first launch in the Device Output log, but otherwise I have no idea how to fix it. Any ideas?

I saw there was a bug fix for this in 5.4 (I’m using 5.6) so is there any chance this is a remnant from that?

Here is the end of the log, which includes the initial startup error. Can include the whole thing if needed.
