iOS Question Iphone 6 suddenly stopped working in debug mode

I have an app that has been in production for about 6 months with no problems.
It has always compiled and run just fine on my iphone 6 (soft Ver 12.5.7) and ipad 6th gen (Soft ver 15.4.1)
I mad a LOT of changes to the interface, primarily in designer script. I did not Add or remove any libs.
I DID update to the latest version of B4A.
I am using B4i ver 8.30 and as far as I know that is the latest.
I made the changes while running the ipad.
When I switched to test on the I phone I am getting the following error:
Error occurred on line: 1189 (BCTextEngine)
Error reading file: Error Domain=NSCocoaErrorDomain Code=260 "The file “emoji-data.txt” couldn’t be opened because there is no such file."

Note that it was failing on a B4X custom library (a modification of BCToast) that I created, it was failing in .initialize, so I removed the custom lib and switched to BCToast Ver 1.01.
It now fails on Toast.Show rather than .initialze.
The iPhone has LOTS of memory available.
The app runs just fine in release mode but I am doing testing that requires a lot of restarts it will be extremely difficult to have to recompile on every change.

Anybody seen this issue?
Thanks for any ideas/help

Try to uninstall the app. Clean project (Ctrl + P) and run again.
