There is a problem with my save plugin in packaged game

ohh but why is it working in the engine but not in the packaged
i got it from here people say it work in 4.26 even in pakaged
(GitHub - PipeRift/SaveExtension: Provides UE4 with a save-game system with support for savegame tags, level streaming and more)


EDIT:
It also say in the read me note from the plugin :
This plugin is for Unreal Engine 4 and actively supports the last 2 versions of the engine.
last 2 versions of the engine it mean it work for 4.26 and 4.27 so there might be a way to fix that
i noticed that another plugin isn’t working well its advanced session if you don’t know what its its like a multiplayer host thing , okey the problem in this plugin is in the packaged the same second as i host it take me out
