Corrupted Ultra Sun save file

[datdarksign]

I've been using checkpoint on my homebrewed 3DS for a couple of months now to backup files on my SD card, edit them in PKHex on my computer, and then restore them to the 3DS cartridge. I've never had any problems before now, but for some reason the save file I've been playing in Ultra Sun is now saying it's corrupted when I try to play it. However, the file can still be read just fine by PKhex. 

I did some searching and found various threads about this issue, but none of the fixes I've seen seem to be working for me. My save file is named "main" and is the only file in the applicable folder. I've attached my save file below. Any help would be appreciated!

How are you transferring the save between your 3DS and computer?
