ArduCam ESP32 UNO PSRAM - Failed to connect to ESP32: Timed out waiting for packet header

My apologies if this question has been addressed. I searched and couldn’t find anything.

Just got my board, and I attempted to upload and run example code provided by ArduCam. I ran into this error (please see below). Please note that the sketch compliles. This error happens when I’m attempting to upload the sketch to the board:

Sketch uses 228668 bytes (17%) of program storage space. Maximum is 1310720 bytes.
Global variables use 15088 bytes (4%) of dynamic memory, leaving 312592 bytes for local variables. Maximum is 327680 bytes.
