When I Play in Stand Alone the Muzzle effect get low and delayed

[AugustoDamasceno]

For some reason, when I Play in the editor the weapon works fine as well as the muzzle effect. But when I play the standalone game or when I package the project, The Muzzle effect gets delayed and low, and I don’t know why.

Any help, please?
