I only speculate that you used
this mod before (for version prior to
v0.11), which probably means that your
Ren'Py game
save (and/or
persistent) files has invalid reference to it.
So, did you used that mod or any other mods (related to Chinese language) before?
The error suggests that it is related to the language selection in the game main menu screen. The
persistent file can be deleted (in both save locations) without major issue, but deleting the
save files, means you have to start over
. Honestly, I don't know if save file is language dependent or not as I have never tried using other languages in this game or any other games (I hope it is not the case).
I don't have
chinese.png (In my installation) too but I didn't get the error (or any error) while launching or playing the game.

You could try 'faking' the
chinese.png by copying the
spanish.png and renaming the copy file to
chinese.png so Ren'Py can find file the file, but it might lead to other error(s) or not.
Other than that, I have no other 'suggestions' or comments to add.
