UE4: The transition between levels seems to work, but it takes me to the current scene. What could be the reason for this behaviour?

Question

unreal engine

I am trying to switch between levels by Server Travel (or Open Level), but it does not transfer me to the desired level, but returns me to the current one. Those. I press the transition to another scene in the main menu, the scene seems to start loading, but as a result, the main menu instantly loads. The fact that the scene is being reloaded can be seen from the debug (infa about initialization appears again).
I checked the path - it is correct. This behavior occurs only in a built project, i.e. when I run the project with the same settings and so on. in any of the editor mods, then everything works correctly. What could be the reason for such an error?
