Hi. Complete beginner here.

Trying to upload a sketch to ESP32-S board. Here is the output from that:

Sketch uses 1035441 bytes (32%) of program storage space. Maximum is 3145728 bytes.
Global variables use 39064 bytes (11%) of dynamic memory, leaving 288616 bytes for local variables. Maximum is 327680 bytes.

The program seems to hang at this point.

When I look at the serial monitor this loop is happening:

This tells you that your esp32 has 4MiB of flash, but your project is configured for 16MiB.

Thank you I upgraded to the latest version of arduino ide which now recognises the biard and sets the correct parameters automatically
