Script never stopping

[Iuigidesu]

Hi, I "made" this script that pastes images from a folder to another folders psd's, it works just as I want it to, however it doesn't seem to stop, once it's finished pasting the images is still loading... something(?). I can open documents and work as usual but the script is still running in the background doing god knows what.
So I was wondering if anyone could help me out figure the issue.
Please have in mind I am not a programmer, I don't even know how i got the script to work in the first place... So any additional feedback would be really useful.

Thanks beforehand!!!!

Here's the code, I can't upload the actual jsx file... 😕

var inputFolder = Folder.selectDialog("Select the folder with your scans");
if (!inputFolder) {
    alert("Select the folder, dummy.");
    throw new Error("No input folder selected.");
}

var outputFolder = Folder.selectDialog("Select the folder with your PSD files");
if (!outputFolder) {
    alert("Select a folder, come on, I won't bite ya.");
    throw new Error("No output folder selected.");
}

var inputFiles = inputFolder.getFiles(/\.(jpg|png|psd|raw|gif)$/i);
var outputFiles = outputFolder.getFiles(/\.(jpg|png|psd|raw|gif)$/i);

if (inputFiles.length === 0 || outputFiles.length === 0) {
    alert("Make sure there are files in both folders.");
    throw new Error("Empty folder.");
}

if (inputFiles.length < outputFiles.length) {
    alert("Not enough images to cover each PSD. Check your input folder.");
    throw new Error("Insufficient images.");
}

OpenFolder();

function OpenFolder() {
    var filesOpened = 0;
    var imageIndex = 0; // Starting index for images

    for (var i = 0; i < outputFiles.length; i++) {
        open(outputFiles[i]);
        var outputFile = app.activeDocument;

        // Determine if the output file is a Double page spread
        var isDoubleSpread = outputFile.width > outputFile.height;

        if (isDoubleSpread) {
            // If DoubleSpread, paste two images
            if (imageIndex < inputFiles.length - 1) { // Ensure there's at least two images left
                pasteImage(inputFiles[imageIndex]);
                pasteImage(inputFiles[imageIndex + 1]);
                imageIndex += 2; // Move to the next pair
            } else {
                alert("Not enough images for a Double page spread PSD. Stopping process.");
                break;
            }
        } else {
            // If portrait, paste one image
            if (imageIndex < inputFiles.length) {
                pasteImage(inputFiles[imageIndex]);
                imageIndex++; // Move to the next image
            } else {
                alert("No more images to paste. Stopping process.");
                break;
            }
        }

        app.activeDocument = outputFile;
        outputFile.save();
        outputFile.close(SaveOptions.DONOTSAVECHANGES);
        filesOpened++;
    }

    return filesOpened;
}

function pasteImage(imageFile) {
    var doc = app.activeDocument;
    
    // Open the image file
    var image = open(imageFile);
    
    // Duplicate the image to the target document
    image.selection.selectAll();
    image.selection.copy();
    image.close(SaveOptions.DONOTSAVECHANGES);
    
    // Paste the image into the active document
    doc.paste();
    
    var pastedLayer = doc.activeLayer;
    
    // Ensure the pasted layer is placed at its original size (no scaling)
    pastedLayer.resize(100, 100);  // Resize back to 100%, in case Photoshop scaled it
    
    // Optionally, rasterize the layer if you don't want it as a Smart Object
    pastedLayer.rasterize(RasterizeType.ENTIRELAYER);
    
    // Rename the layer to ensure uniqueness
    pastedLayer.name = getUniqueLayerName("Scanned Version");
}


function getUniqueLayerName(baseName) {
    var layerCount = 1;
    var uniqueName = baseName;
    var layerExists = true;

    while (layerExists) {
        layerExists = false;
        for (var i = 0; i < app.activeDocument.layers.length; i++) {
            if (app.activeDocument.layers[i].name === uniqueName) {
                layerExists = true;
                layerCount++;
                uniqueName = baseName + " " + layerCount;
                break;
            }
        }
    }
    return uniqueName;
}

Please provide a set of folders/images for testing. (Feel free to flatten and blacken the images if the content is sensitive.) 

Why are you copy/pasting instead of placing?

The idea is that you run the script, first select the "Scanned Raw" and then the "Cleaned" folder. It should paste the images accordingly.
I tried placing the image directly, but for some reason it will paste them at 50% their original size. So this way pastes the image at their original resolution

[c.pfaffenbichler]

Do the images have the exact same resolution?

Yup, I tested it in 1200px and 2048px tall images and the thing worked fine, but when I tried with 4800px images, it would paste them in half the size, so I wanted a solution that worked in every scenario, and I think this does.
