3d widget does not work properly in packed game


I use a 3d widget which the players can interact within the game world.

Everything works great when the game is started via the editor or as a standalone game.

But as soon as I pack the game, the buttons can be pressed but they don’t do anything.

It makes no difference if the game is started in fullscreen or in a window, the problem must be the packing itself.

Thank you already
