The lowest frequency value for tone using an esp32-c3 appears to be 153 (when simulated on Wokwi).
Note that if the frequency value changes before the duration value expires, the duration is reset.
Therefore, the buzzer will be on continuously until the tone value remains constant for longer than the duration value.
Example
from esp32-esp32s2-analogwrite.

Pushed an update that limits the minimum tone frequency to 153 when using the ESP32-C3.
