How do I fix this exception?

[natsayurica]

I'm sorry, but an uncaught exception occurred.

While running game code:
File "game/script.rpy", line 31, in script call
call example_chapter from _call_example_chapter
File "game/splash.rpy", line 286, in script
return
Exception: Could not find return label (u'C:\\Users\\Natsayurica\\Downloads\\renpy-7.1.1-sdk\\DDLCModTemplate-v0.1.0/game/script-example.rpy', 1540145146, 0).
