Problems when any I2C sensor is connected to I2C connector.

in Elecrow HMI Display

I have a BH1750 I2C sensor connected to the I2C connector of 7" V3.0 HMI.
This model has SDA=19 & SCL = 20. (no other pins are available)
The senor works fine in a standalone code (no LVGL)
But with LVGL included, the sensor stops reading, and the entire code is laggy.
Can anyone tell me whats happening?
