My game is split screen after packaging on windows

I have fight game I want to release on windows, it has no split screen and works in the editor fine. But when I package and starts the game the level is split screen why?

that is strange. Does it act that way if you Play Standalone instead of Play In Editor?
For the Play options on the dropdown do you have more than one player?
In the project settings what is selected, splitscreen or no?

Do you have sny C++ or blueprint nodes or plugins that enable or disable splitscreen?

I solved it, thanks to you. Based on the questions you asked me, i decided to disable all the plugins that i don’t need for my project and also changed the number of players to two in the active play dropdown. i repackaged the game and the split screen is gone.
