Hi.

  1. This issue seems like a problem with Wi-Fi credentials. Please double-check the credentials and make sure that you’ve not mistyped any character.
  2. Is this the bare chip? Or a full-featured module? If it is the bare chip, how are you connecting it to your computer?
  3. Press the ESP32 on-board RST button after uploading the code. Check the power source of your board. See our troubleshooting guide bullet 8: https://randomnerdtutorials.com/esp32-troubleshooting-guide/ 
  4. See our ESP32-CAM troubleshooting guide: https://randomnerdtutorials.com/esp32-cam-troubleshooting-guide/

Try to solve one problem at a time. I hope this helps.
