Not Installing JKSV Correctly and Corrupting ACNH Saves

[TrueTexan21]

This issue started happening randomly across 2 consoles. Randomly I started getting corrupted saves notifications after loading saves for ACNH. I would then need to quit the game, re-install the save folder from my computer to both consoles, uninstall JKSV, boot back to payload, re-install JKSV, and then load up the save again for it to load up an ACNH save. Now on one of my consoles, no matter how I try to install JKSV I get an app with an exclamation mark and a gray icon when I go to the hbmenu. I've used FTPD, I plugged my Switch into my computer, and I've removed the SD card from the Switch and put it into my computer to install JKSV. I've used a version I downloaded in 2023 and I've used a version of JKSV I downloaded today and am still getting the same result. Any suggestions?
