      Arduino IDE 2.2.1
      ESP32 board def. ver. 2.0.13
      M5Stack board def. ver. 2.0.7
      M5Stack library ver 0.4.5
      M5_ENV ver. 0.0.8
      All recently updated.
      Sketch is the example from the Github repository:
      Unit_ENVIII_M5Core.ino
      When I comment out this:

      /*
          if (sht30.get() == 0) {  // Obtain the data of shT30.  获取sht30的数据
              tmp = sht30.cTemp;   // Store the temperature obtained from shT30.
                                   // 将sht30获取到的温度存储
              hum = sht30.humidity;  // Store the humidity obtained from the SHT30.
                                     // 将sht30获取到的湿度存储
          } else {
              tmp = 0, hum = 0;
          }
          */
      

      it does not crash, but of course it does not display the temperature!
      So...it points to the "sht30.get()" function.

      When I replace it with inline code:
      (and declare this: unsigned int data[6];)
      Wire.beginTransmission(0x44); //0x44 for M5Stack ENV (0x45 is DFRobot)
      Wire.write(0x2C); //show all the "wheels and gears"
      Wire.write(0x06);
      Wire.endTransmission();
      delay(50);
      Wire.requestFrom(0x44, 6);
      data[0] = Wire.read();
      data[1] = Wire.read();
      data[2] = Wire.read();
      data[3] = Wire.read();
      data[4] = Wire.read();
      data[5] = Wire.read();
      tmp = ((((data[0] * 256.0) + data[1]) * 175) / 65535.0) - 45;
      hum = ((((data[3] * 256.0) + data[4]) * 100) / 65535.0);

      The sensor works!

      Cheers, Terry!

        I has same problem. I solved it by adding sht30.init(); to the setup() function.

        SHT3X sht30;
        QMP6988 qmp6988;
        float tmp = 0.0;
        float hum = 0.0;
        float pressure = 0.0;

        void setup() {
        M5.begin();
        Wire.begin();
        sht30.init();
        qmp6988.init();
        }

        this is missing in the example
