Script sometimes working sometimes not working

So I got this script from the community post and tried this script in InDesign 2023, the script was running and working for few times, but after giving it another try, the script was not running and working anymore, there's no error message popup, so just wondering how to fix this script? 

var scriptName = "Change automatically frame with hyperlink text into hyperlinked frame",
debug = false, // for debugging only
doc;

app.doScript(PreCheck, ScriptLanguage.JAVASCRIPT, undefined, ((File.fs == "Macintosh") ? UndoModes.ENTIRE_SCRIPT : UndoModes.FAST_ENTIRE_SCRIPT), "\"" + scriptName + "\" Script");
//===================================== FUNCTIONS ======================================
function Main() {
	try {
		var hyperlink, sourceText, textFrame, storedName, newSource, newHyperlink,
		doc = app.activeDocument,	
		hyperlinks = doc.hyperlinks.everyItem().getElements();

		for (var i = 0; i < hyperlinks.length; i++) {
			hyperlink =hyperlinks[i];

			if (!hyperlink.source.hasOwnProperty("sourceText") || 
				hyperlink.source.sourceText == undefined
			) {
				continue;
			}
		
			sourceText = hyperlink.source.sourceText;
			
			textFrame = sourceText.parentTextFrames[0];	
			if (textFrame.extractLabel(scriptName) == "processed") continue;
			
			storedName = hyperlink.name;
			
			try {			
				newSource = doc.hyperlinkPageItemSources.add(textFrame);
			}
			catch(err) {
				if (debug) $.writeln(err.message + ", line: " + err.line);
				continue;
			}
		
			newHyperlink = doc.hyperlinks.add(newSource, hyperlink.destination);
			hyperlink.remove();
			textFrame.insertLabel(scriptName, "processed");
			
			 // clear the "Hyperlink" character style
			if (sourceText.appliedCharacterStyle.name == "Hyperlink") {
				sourceText.appliedCharacterStyle = doc.characterStyles.item("[None]");
				sourceText.clearOverrides();
			}
		
			newHyperlink.name = storedName;
		}
	}
	catch(err) {
		alert("Something went wrong: " + err.message + ", line: " + err.line, scriptName, true);
	}
}
