It happens with Processing 4.3 and 4.3.1 on mac and windows. I haven't tested older versions of processing. I get the same error message if i click the menu item for optimizing the sketch.

If i create a new project with just an empty setup method, optimizing and exporting works fine. My project consists of 20 files with several thousand lines of code. Maybe that's a problem? I tried to reproduce the error in a new project but failed to do so. I was able to find a possibly related problem though. If i create a new project with the following code and hit the optimize button, it fails with the runtime error "IllegalStateException: size() cannot be used here, see https://processing.org/reference/size_.html".

/*
void setup() {

}
*/

void setup() {
  size(600, 600, P2D);
}

The error disappears if you either remove the comment or rename the function inside the comment to, for example, test(). Exporting the sketch works fine tough. I removed all the multiline comments from my larger project but it made no difference.
