error: no matching function for call to 'TwoWire::TwoWire(int, int)'

I get an error

I think the 3rd argument is missing. But I don't understand what type it should be. \ArduinoData\packages\rp2040\hardware\rp2040\2.7.1\libraries\Wire\src/Wire.h file:

TwoWire::TwoWire(i2c_inst_t *i2c, pin_size_t sda, pin_size_t scl) {
    _sda = sda;
    _scl = scl;
    _i2c = i2c;
    _clkHz = TWI_CLOCK;
    _running = false;
    _txBegun = false;
    _buffLen = 0;
}

arduino version:

1.8.19 (Windows Store 1.8.57.0)

@g-struchin Got the same error, fixed it by removing the line TwoWire CustomI2C0(20, 21);, and add / update the following three line instead:

Wire.setSDA(20); // Add this
Wire.setSCL(21); // Add this
if (!mpu.begin(0x68, &Wire, 0)) { // Replace &CustomI2C0 with &Wire
...

Check the Arduino-Pico documentation for more infos.

Fixed it with TwoWire WireMPU(i2c0, 20, 21); and if (!mpu.begin(0x68, &Wire, 0)). This way will prevent any conflicting errors if you are using any other sensors.
