How break with script to anchored object release

Marc Autret Method:

var a = app.selection[0].allPageItems, t;  
  
while( t = a.pop() )  
    {  
    t.isValid &&  
    t.hasOwnProperty('anchoredObjectSettings') &&  
    (t.parent instanceof Character) &&  
    (t=t.anchoredObjectSettings).isValid &&  
    t.releaseAnchoredObject();  
    }  

Jongware Method:

n = app.selection[0].textFrames.length;  
while (n >= 0)  
{  
     try {  
          app.selection[0].textFrames.anchoredObjectSettings.releaseAnchoredObject();  
     } catch(_) {}  
     n--;  
}
