Final Fantasy X crashes/freezes right before going inside of Sin

Solution 1:

I haven't found anything relating to the original PS2 game, but a lot of people have been reporting a similar glitch were the game effectively soft locks during the Sin fight in the HD remastered version.

The reports of this happening are during the use of certain Overdrive moves or Summons, where the game simply stops responding. It doesn't freeze, the game continues, then nothing further happens.

As far as I'm aware, while this glitch is incredibly game-breaking, I haven't found any evidence of a fix for this, or any advice on how to manage it.

As you can see, these were posted several years apart, so the issue has never been resolved, and some users have posted about the issue occurring regardless of platform (PC, PS4, Switch, etc).
