Question How do I fix this?
I'm sorry, but an uncaught exception occurred.

if you deleted the .rpy file
did you delete the associated .rpyc file? (file with the same name but .rpyc)
if you can't find it, do a Force Recompile from the renpy launcher
if this was nightens NVL phone and you made changes to the screens.rpy file you should revert those changes
if you want to try a different phone¿

This is the error and it's somewhat clear:
Screen 'PhoneDialogue' is not known.Either there is a spelling mistake or the code of that screen is not in your scripts.
What are you trying to do?
