Customer's .sav file crashes packaged game and editor

The save/load system has so far worked perfectly for me, however, all of a sudden, I have a .sav file from a player that crashes both the packaged game and the editor as soon as the “Load Game from Slot” node is reached. Unfortunately, this means I’m not sure where to begin when attempting to fix this issue as it works perfectly for myself and all other players, so I would very much appreciate some support.

If you would like me to send the .sav file in question or the project to you, please just let me know.
