The ESP32 CAM (WROOM) already has the 4MB of PSRAM RAM it needs to run. I'm sure you do not need to plug in a memory card if you are using the proper ESP32CAM.
I did not see the normal message sequence of upload a program to the ESP32 CAM.
After the jumper is in place, then press the button, the ESP32CAM will give a message that it is ready for upload. Then start the upload.
That tells me your program tried to read a memory address that is not there.
Install the ESP Exception decoder and use it, look it up on the internet.
Post a pick of your setup. Especially how you've plugged in a memory card.
