Is a good sign.

Right after this you may need to unplug it from USB and plug it in again to re-start the sketch.
Maybe try my 'Generic_tick_tock_serial_test' sketch with Serial output and no display, then move on to the HotHead sketch.

(In Arduino IDE)

Sketch uses 748665 bytes (23%) of program storage space. Maximum is 3145728 bytes.
Global variables use 45656 bytes (13%) of dynamic memory, leaving 282024 bytes for local variables. Maximum is 327680 bytes.

Can you copy / paste the actual error message from the comm window at the bottom of Arduino IDE ?

Then we can start troubleshooting.

I also made a GitHub repository for new users with setup help and simple examples for troubleshooting here:
https://github.com/teastainGit/LilyGO-T-display-S3-setup-and-examples

Everything I could tell you in the next paragraph is here, but it is a long read, because the LilyGO T-Display S3 is a complex high performance board, very challenging.

The S3 variant requires using the Boot button and the Reset to enter into download mode. There are three ways to do this, so try them in order.
