esp32-cam uploads once error free and then never again

I have 2 x esp32-cams.

I installed the board drivers and the upload the sample code for the first time and it loads error free, but no serial output.
I reopen the serial monitor and then try to upload it again and on the second time it fails with

Arduino: 1.8.13 (Linux), Board: "AI Thinker ESP32-CAM"

Sketch uses 2100647 bytes (66%) of program storage space. Maximum is 3145728 bytes.
Global variables use 53552 bytes (16%) of dynamic memory, leaving 274128 bytes for local variables. Maximum is 327680 bytes. v2.6
Serial port /dev/ttyUSB1

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

and I cannot get it to reinstall/reupload anything again.

Then I doubt myself and connected esp32-cam number 2. I connect to it, it uploads the same code error free. I still get no serial output and see nothing new on my network.
I try and reload the software and it fails again.

What is up my esp32-cams? How do I get an image to load?

I used this as a guide in connecting

It would not have uploaded the first time if it was connected wrong though.

never mind this post. I am past this an don a new error now.
