I'm sure this isn't the first DirectX Error thread that's been posted here, but this one's a bit of a curiosity.

I've had the crash on dungeons, which was always annoying, and I didn't think too much of it until I started seeing a pattern. the more I looked into this pattern, the clearer it became, until I realized that it was VERY consistent.

Any and every time the song "Insatiable (Primal Remix)" [better known as the "miniboss theme" from Shadowbringers dungeons] plays, I get the error and crash. It only happens on the first two bosses; this crash has never happened on the last boss (where a different theme plays), on Mt Gulg (where a different track plays for the bosses), or any dungeons outside of the Shadowbringers expansion.

Muting the music did nothing, and reinstalling the game (complete repair, complete uninstall/reinstall) did nothing to abate this problem; in fact it made the crash happen earlier into the track than before. The only workaround I have been able to do is slide the dialog box into a corner and ignore it, but when I do, I lose all sound, as well as all animations including some markers and boss effects.

my guess is a corrupt file, but no amount of repairing or reinstalling has seemed to have any effect on it, so at this point I'm a bit at a loss.
