I need help for launch failed

Hello, when I run my project and I have an activated plugin, I get an error message :


LogPlayLevel: Error: ERROR: Stage Failed. Missing receipt 'E:\Projets Unreal engine\Unreal Engine\PlayerOne\Binaries\Win64\PlayerOne.target'. Check that this target has been built.

You may have to build the UE4 project with your IDE. Alternatively, build using UnrealBuildTool with the commandline:
UE4Game <Platform> <Configuration>

when I activate “niagara plugin”, “plugin substance” or “houdini engine” i get a launch failed.
but if I disable these plugins, everything works well.

I’m working only in BP. I use the engine in its latest version
if I delete the “intermediate” folder and the “saved” folder of my project, I get another error
