ESP32 Compilation error: exit status 1

It's probably a "new guy thing," but I need help with an error when attempting to upload to my ESP32 WROOM board. The error that comes in is:

exit status 1

Compilation error: exit status 1/>

For a program, I simply used the basic void setup / void loop with no other code to rule out syntax errors.
I am using Arduino Version 2.2.1

If you own 30-pin ESP32 Classic Board, then select ALKS ESP32 Board in IDE 2.2.1 and upload the following sketch which works well for me.

#define RLED 2//onboard BlueLED

void setup()
{
  Serial.begin(115200);
  pinMode(RLED, OUTPUT);
}

void loop()
{
  digitalWrite(RLED, HIGH);
  delay(1000);
  digitalWrite(RLED, LOW);
  delay(1000);
}

I normally use IDE 1.8.19 and select the board as "ESP32 Dev Module".
