Each ESP32-POE is tested empirically after manufacturing. The test includes programming at least two times.

Double check cabling, port selection, programming settings and configuration. Try with another software tool.

Try reinstalling the CH340 driver.

My advice is to also first try with the tools supported by the chip manufacturer Espressif -  like esptool, ESP-IDF, ESP32 package for Arduino IDE.
