Esp32-cam upload issues

Hi I am using the MB board to connect the ESP32 S-Cam to my computer to upload the Camera Web Server sketch. I have done all the setup procedures. The com port has been found the lights on the board are lit. I have chosen #define CAMERA_MODEL_AI_THINKER
I have both lines in the additional boards manager slot
https://espressif.github.io/arduino-esp32/package_esp32_index.json
https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json
Com 3 is selected in device manager, so it made the connection.
When I click on Get board Info, it provides the proper response.
Therefore the board is connected, but I get the following when I try to upload the Camera Web Server Sketch.
A fatal error occurred: Could not open COM3, the port doesn't not exist.

Any Ideas

Are you using this setup (Fig-1)? If yes, upload a simple on-board LED (connected at GPIO33) blinking program and check that it works.

Figure-1:

The motherboard relies on a modified version of the esp32cam so it can reset it, if you bought the motherboard separately it could be that your esp32cam does not have this which could be your issue?
in this case you will need to press the program button on the esp32cam when connecting power to put it in to program mode.

Thanks for the replies. The MB came with the CAM. I will try both of your suggestions.

I pressed the boot button before plugging in the USB, and was able to get the ESP to recognize the COM port, but I still cannot upload any sketches. Not even a blank one.
See Error results:

might be confusing things..
Looks like you're using the latest developer release, lose the dev url and load latest stable release 2.0.15, that's the other url you already have without the dev in it..

also looks like really old version of IDE but still thinking you need the stable release of esp32..

good luck.. ~q

Thanks, I'll give it a try

I am ready to give up on this ESP32 CAM
Now I get this error, and I don't know why. I can't even find this STD line to try and change it.
