Posting pictures of code makes it very hard to see, better to post the code and copy/paste the actual error message. (also, better to not show your actual ssid and password)

For your particular problem, for some reason WiFI.begin does not want the ssid to be a const char*, but instead a char*.

//replace this line
const char* ssid = "your_SSID";
//with
char ssid[] = "your_SSID";

What WiFi library is that? arduino one takes const char *


int begin(const char* ssid, const char *passphrase);

but ESP also has overload to take const char *, maybe your library needs updating?
