Welcome to the forum

Moved to Programming category

Please post the sketch that produces the error, using code tags when you do

alright thank you!

also here is the sketch

const int led = 13;

void setup() {
  // put your setup code here, to run once:
  pinMode(led,OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(led,HIGH);
  delay(500);
  digitalWrite(led,LOW);
  delay(500);
}

Thank you

The problem does not appear to be with the sketch. Exactly which board have you got selected in the IDE ?

Can you compile any other sketches for the nano every, such as the example blink sketch?
Possibly a bad install of the IDE, or an antivirus program either deleted a file, or is interfering with the files created during the compilation.
