Help: ESP32‑MKR1000 hive monitor keeps resetting on high humidity readings

i just wired a sht31 to the esp32‑mkr1000 to log hive temp/humidity every time the humidity goes above 80% the board resets i checked the power supply 5v 2.5a and the sht31 is fine the code uses the i2c bus at 400kHz maybe the sensor is pulling too much current or the i2c clock is too fast for the sht31 i also saw a forum post about the sht31 needing a pull‑up resistor on sda/scl any ideas tbh i’m not sure if it’s the sensor or the board i tried a 10k pull‑up and still resets i’m using the arduino core for esp32 any suggestions thanks
