Exception: not a compressed Palworld save, found b'PlM' instead of b'PlZ'

Got to the point of running the script and getting this output:

Converting C:\Users(USERNAME)\Desktop\TestFolder/Level.sav to JSON...Traceback (most recent call last):

I have the Players folder with the two saves, old and new, for my character in the TestFolder, along with the script, Level.sav, LevelMeta.sav, LocalData.sav, and WorldOption.sav files.

Any help is appreciated! I'm trying to save my character levels/experience. Also, I assume yes, but would we see an updated modified time on the player files or any of these files after running the script successfully?
