Compiling for attiny1616 using default settings fails

When compiling an empty sketch for the attiny1616 using the default settings in Arduino IDE 1.8.13 the error below appears. This error appears for the same sketch and settings in all the attinyXX16 boards

Sketch:

void setup() {
  // put your setup code here, to run once:

}

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

}

Settings:

Result:
