ESP32 photo every 10s with deep sleep

I'm using example code from https://randomnerdtutorials.com/esp32-cam-take-photo-save-microsd-card/

It should take a photo whenever the RST button is pressed, then go to Deep Sleep and again and again...

That's working fine, but instead of pressing the RST button each time, I want to use a timer, to take a photo every 10s and then go to deep sleep and again and again...

Here is my code - combine example from randomnerdtutorials and deep sleep example from https://lastminuteengineers.com/esp32-deep-sleep-wakeup-sources/

Here is my code:

  IMPORTANT!!! 
   - Select Board "ESP32 Wrover Module"
   - Select the Partition Scheme "Huge APP (3MB No OTA)
   - GPIO 0 must be connected to GND to upload a sketch
   - After connecting GPIO 0 to GND, press the ESP32-CAM on-board RESET button to put your board in flashing mode

But for some reason it's not working, this is output from serial monitor:

SD Card Mount Failed

I don't understand why it's saying "Wakeup caused by touchpad" when it's should be timer & why I'm getting the "SD Card Mount Failed" when before it was able to save a photo without any problem.

Thanks for the help.
