The "Niagara" fire is not displayed in the compiled project

[Viperator666]

When compiling the project, the Niagara fire does not appear at all (there is sound, additional lighting, everything is there, but there is no Niagara)
Everything is fine in the editor and in the simulation. Maybe some settings need to be changed in the project or in Niagara itself?
Thanks

What’s interesting.
Not all of Niagara is not displayed in the finished game.
Created a new project, added three different effects, only the “explosion” is displayed. Both flames are not visible.
