High Resolution Screenshot Issue in EXE Build (Win10)

I created a high-resolution screenshot setup in Blueprints, and it works perfectly inside the editor.
However, after packaging the project into an EXE on Windows 10, the result is wrong/distorted.

My command is:
HighResShot 3000x2000 0 0 0 0 0 1 1 1

Any idea why this happens and how to fix it? Could it be related to packaged build settings or viewport scaling ,
