I can't click on the Main Menu

Hi, I’ve created a Main Menu that works perfectly when I press Play in the editor. However, after packaging the project, I execute the game and I can’t click anywhere on the Main Menu, so I can’t start the game. When I just had my level (without main menu), I could use both keyboard and mouse, now with the main level I can’t click on Play to play . The keyboard doesn’t work either on that Main Menu. I’m not sure if there’s something I haven’t configured properly to make the mouse work correctly when launching the executable game.
