When loading the courses in the Kart Race menu in order, everything works as expected. Selecting the courses in a strange order (for example, going back to Beginner after loading up Standard or Expert) will cause the game to crash at 0x626040, which appears to be an njTranslate call related to the street lamp positions for the individual course pieces.
Disabling the "Restore Posters" fix under the "Cart Stages" category fixes the crash, meaning that the issue likely traces back to a problem with the removed posters that was "fixed" by disabling them outright.
