"Load Files Into Stack" Error 24

Quit Photoshop.

Move the support script in Presets/Scripts/Stack Scripts Only/LatteUI.jsx to the Desktop.

Then, save the code below with the same name to the same location as above.

Restart Photoshop.

If this works, then great! If not, replace the updated file with the original that you moved to the Desktop.

I'm not sure why you are getting that error, it's looking for spaces around a colon : character or just a colon character, which comes from the support script found in Presets/Scripts/Stack Scripts Only/LatteUI.jsx

Perhaps try running the script from selected files in Adobe Bridge.

As an alternative to the overly complex Adobe script, you could try some custom scripts that I created, which are easier to troubleshoot and modify.
