Hello team

I'm attempting to have my ESP32 generate a HTTPS Access Point connection. Can this be done with an ESP32?

I am using Platformio as my build environment running on a Raspberry Pi 4.
The source code can be found at the following github link: https://github.com/tsbiberdorf/httpsConnection.git

The code compiles and loads fine, but when I make the connection to my ESP32, the ESP32 resets with the following error message.

Thanks.

Any chance you can decode that backtrace?

@threeboys is right, His example does not work, nor does this one. It resets as well.

sorry for the delay, I had problems getting decoder working. Below is my decoded results:
