How do you power the ESP32-POE? Is it powered from the same source as the LED strip? If not - did you measure if there is voltage difference between the two grounds? Can you give me a diagram or sketch or schematic on how the hardware connection and power supplies and grounds are connected?

This board has 5V on the data lines and incorporates many level shifters. It is specifically designed to operate 5V LED strips.
This is not the case with ESP32-POE. I guess your LEDs are 5V while ESP32-POE is 3.3V. You said you used level shifter, but did you use it on the GPIO line?
