Have you read the wiki regarding how to compile?
yes i have
What version of the Arduino IDE are you using?
i am using 2,3,0
What version (commit date) of the Arduino core for the ESP32 are you using?
i am using version 2,0,14
Are you using the master branch of Grbl_ESP32?

Have you made any edits or configuration changes (list them) to the firmware?
i changed the ssid, password and the machine.h to run 3axis

Your problem is probably caused by a change in a later version of the compiler. When we stopped working on Grbl_ESP32, the C++ compiler was a generation or two older. We don't support Grbl_ESP32 any more; all of our current work is on FluidNC.

thank you for your reply. i also have older version of arduino ide so that might work?

[MitchBradley]

It is up to you. As I said, we are not supporting Grbl_ESP32 any more.

Hi. I tried older version still the same error so i tried diferent versions of esp32 packages and i got diferent errors. Now i am trying version 1,0,2 and i got this error:
