### Kivy Graphics `IndexError` on Application Startup

[Gorkem Cismel]

  Hello,


  I'm encountering a crash on startup with the error IndexError: list index out of range originating from
  Kivy's internal graphics engine.

  This error is typically caused by an imbalance in the graphics instruction stack. After reviewing the
  code, the likely cause is redundant loading of .kv files.


  The main slothrunner.kv file uses the #:include directive to manually load the .kv files for each screen
  (e.g., profilescreen.kv, settingsscreen.kv). However, Kivy's engine is designed to automatically find and
  load these files because their names match the corresponding screen class names (e.g., ProfileScreen ->
  profilescreen.kv).


  This double-loading process likely corrupts the graphics state, leading to the crash.

  To fix this, you should remove the following lines from the end of the `C:\Users\cisme\Desktop\Game
  projects\sloth_runner\kv\slothrunner.kv` file:


  `kv
  #:include settingsscreen.kv
  #:include profilescreen.kv
  #:include how_to_play_screen.kv
  `


  Removing these lines will eliminate the redundant loading and should resolve the IndexError.

This looks like a response to a previous message - but I can't seem to find the original post.

Kivy does not automatically load screen class kv files.  It will try to load a kv file with the same name as the App class.  

The log will show redundant loads of kv files.

Thank you for your support. The problem seems to be solved for now. I hope I can finish the project without encountering any further issues :)
