Fatal Error after packing project

[Crossroad1000]

Currently, I'm building my project that is made with SaveExtension.
I'm using Unreal Engine 5.1.1 and packing my project for Windows.
In the editor, I'm able to save my level and load it again after stopping and restarting my game. However, I'm now building the project and I'm getting a fatal error when I want to load my game.

I have changed the settings on the serialization but without success, I keep getting the same error.

Here is the error it gives me after packing my game and playing it:

I hope you know a way to fix this as I need this plugin to work!

Many thanks :)

Update

Maybe I found the problem but no solution yet.
It looks like the problem is when switching levels and game modes.
In the editor, when switching different levels and game modes, the display name/ file path is all 0 and equal.
But after packing I noticed that everytime I open my level for the first time it gives me this file path:

Here I'm able to load the game as it was saved with this same file path.
But when I jump back to the menu level and open the game level again, the file path changes (unique ID):

Is this what could be the problem when loading the saved data? Should it be the same file path as it was saved on?
And is there a way to keep the same file path when switching levels?
