Program failing to load Level.sav file when transferring

[PixelPancakee]

Hey peeps,
I have run into some trouble when trying to fix my save from the recent major bug. Whenever i try to use the program to restore my world before the crash, it throws up an error (i have attached the CMD error it threw). Not sure if this is due to a corrupted file or something else.

I do have the LocalData.sav and LevelMeta.sav as well, i can see the LocalData.sav hasnt been changed since the crash

Any help would be appreciated :)

p.s. you are amazing for writing this program to have a fix for the community
