I think the main issue, that your sketch does not upload correctly.
Put the ESP32-S3 in upload-mode manually: Press and hold the BOOT button, then shortly press the RESET button and release the BOOT button.
(This also disconnect the serial connection and the port may change again.)
Upload the sketch and watch the log for errors.
Then manually reset the ESP again and open the Serial monitor.
If any error happens, please post the full log here.
