The log looks very much like using a wimpy USB/serial adapter unable to power the ESP32 to boot to Wifi. What happens with mains power instead is hard to guess.....

Hi

I only use USB/Serial to flash. Then, I connect the POW to 230V. First time boot after flash, POW shows AP tasmota-xxxx-xxxx for 20 or 30 seconds, I can connect to this WiFi but not to device....and Tasmota AP goes down and disappears... It is only for first time boot up after flash...all other power cycle didn't shows the tasmota AP again.

You also used the USB/serial adapter to provide the logs you showed, thus no basis for guessing what happens when using mains instead.

In your opinion, how can I take the logs when connected to 230V?
