FREERTOS Guru mediation error, esp32

Projects Programming

I am attempting to use FREERTOS. Using 2.09. I have tried various examples, all blow up in, I think the same way. Currently using an ESP32 DEVKIT, although I am really trying to use the C3. So getting down to simplest possible program:

TaskHandle_t Task1;


void setup() {
  Serial.begin(115200); 
  Serial.print("setup() is running on core ");
  Serial.println(xPortGetCoreID());

  xTaskCreatePinnedToCore(Task1code,"Task1",20000,NULL,1,&Task1,1);   
  Serial.println("Past xTaskCreate...????");                        
  delay(500); 
  
}



void Task1code( void * parameter ){
  Serial.print("Task1 is running on core ");
  Serial.println(xPortGetCoreID());
  Serial.print( "Task1 Stack WATERMARK " );
  Serial.println( uxTaskGetStackHighWaterMark(NULL) ); 
  delay(10000);

}

void loop() {
  //Serial.print("loop() is running on core ");
  //Serial.println(xPortGetCoreID());  
  //delay(10000);
}

All compiles and loads, no problemo.
I get:

Apparently it creates the task, hits it one time, then blows up. The stack size seems to use most of what I put in there--doesn't make a difference.
Obviously, I am doing something wrong, simply wrong. I am primarily a hardware guy, tend to go down rabbit holes on this kind of stuff.
HELP?
And, thanks in advance.

A task should NEVER return. It should be an infinite loop. There's an example in the Arduino IDE:

Of course.
Dumb de dumb dumb.
Thanks so much.
Made the change, things now starting to make sense.
