I am getting this watchdog Timer error while doing a simple task in arduino with esp32

i have seen a lot of forums where this problem is dicussed but nothing seems to work. I am working with esp32 and it was all fine untill out of nowhere this watch dog timer error came up. I am new to it so i cant really fix this. I have another code but i copied a very simple chunk of it and created a new file but watch dog timer error is appearing here too. I dont know what the issue. it said idle0 is not resetting watach dog timer and "wifi" task is running on cpu0.

ERROR LOG E (42418) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time: E (42418) task_wdt: - IDLE0 (CPU 0) E (42418) task_wdt: Tasks currently running: E (42418) task_wdt: CPU 0: wifi E (42418) task_wdt: CPU 1: IDLE1 E (42418) task_wdt: Aborting. abort() was called at PC 0x400d96f7 on core 0

I have tried running my task on cpu1 or core 1 too but wifi is automatically running on cpu or core0. And getting the same error. have also tried adding delays but nothing works.



char *wssid = "PTCL-TB";
char *wpassword = "pakistan";

bool connected2Wifi = false;
void setup() {
 // put your setup code here, to run once:

 Serial.begin(115200);
 delay(10);
 Serial.println('\n');

 WiFi.begin(wssid, wpassword);             // Connect to the network
 Serial.print("Connecting to ");
 Serial.print(wssid);

 while (WiFi.status() != WL_CONNECTED) { // Wait for the Wi-Fi to connect
   delay(500);
   Serial.print('.');
 }

 Serial.println('\n');
 Serial.println("Connection established!");  
 Serial.print("IP address:\t");
 Serial.println(WiFi.localIP()); 
}

void loop() {
 // put your main code here, to run repeatedly:

} ```

I want to connect to wifi in this task. It's very simple and i have also copied it from a reliable source whose code was running. but the error seems to be rigid.

Go to Tools -> CPU Frequency and set it to 160, 80 or 240 MHz (the ones that support WiFi/BT).
