Can't Export Unmodified .sav file

[godernst]

I can't make any edits to a .sav file using the latest version of PKHex - even if I try to just export the unmodified.sav file I get an Array boundary exception.

I was able to modify a .sav file from the same game a few days ago, but don't want to revert to that version as my daughter will lose the progress she's made over the past week (trying to make  the grinding a bit easier for a first-time 6-year-old player but not fully-explain to her how to hack a save and quickly level her Pokemon).

This is a LeafGreen save.  File attached.

Exception Details:
System.IndexOutOfRangeException: Index was outside the bounds of the array.
