My CCS811 from CJMCU does not works after flashing completed.

Before flashing it was working good. After i flashed it, It does not works with the library.

Its says I2c Error every time, i have scanned i2c bus with scanner sketch, the sensor shows the address 0x5A.

Please help me. i have tried to reflash it with the flasher example, but it never flashes or connects.

I removed everything except these lines :

Wire.begin();

// Enable CCS811 ccs811.set_i2cdelay(50); // Needed for ESP8266 because it doesn't handle I2C clock stretch correctly

delay(5000); //Serial.println(""); bool ok= ccs811.flash(image_data, sizeof(image_data));

And the module re-flashed and working again. Something in the flash sketch stopped flashing.
