Took a break for a year, came back to 90% of my custom charts not loading

Trying to troubleshoot. Im on the quest 3. Ive already tried:

-refresh button -deleting everything, reloading, putting everything back, reloading -redownloading charts

None of them are broken files and they're in the correct folder.

Only 12 of my 60 custom charts work. Its kinda ruining my desire to play the game again.
