iOS Question app fail start after "Copying updated assets files"

[SlashIT]

Hello to all, I have a very serious problem that I can not solve: after compiling the app without problems (both locally and remotely), almost never start. Debugging me back this:

Copying updated assets files (56)

Do you have any idea? If I restart the installation several times (only in debug, production does not work), the app starts ... I'm going crazy...

Thanks

Have you tried to uninstall the app from the device and then run it?
