The op might want to learn more about the tone32.h library being used and how the numbers being sent to the tone32 library affect the ESP32's LEDC API, clicky clicky, and how those numbers are effecting the HardwareTimers and how the pitches.h numbers are interacting with the hardware timers.

As @Idahowalker said, just change the frequency will solve your reboot issue, such as

...
tone(BUZZER_PIN, NOTE_C7, 500, BUZZER_CHANNEL);
noTone(BUZZER_PIN, BUZZER_CHANNEL);
delay(500);
tone(BUZZER_PIN, NOTE_DS8, 500, BUZZER_CHANNEL);
noTone(BUZZER_PIN, BUZZER_CHANNEL);
delay(500);
