From the trace you posted, this line:
AttributeError: module 'pygame_sdl2.locals' has no attribute 'K_10'
Means that there is an unknown "key code" being entered, with value K_10
"K_10" is not on the list of supported keycodes for the Pygame_sdl2 library that is part of renpy (

So how are you inputting the patron code? copy and paste? could there be an extra non-standard character there somehow?
or do you have some magic keyboard where the number key goes beyond the 0 to 9 range
