There is a hill near that Bazaar that can be stood on and hovering under or above a stand-able surface with chus does not crash the game. So you may have been hovering under that if you used chus.
I tested this in Gerudo valley earlier (the clip that you'd do if you failed the cucco jump and fell) and no crash either. Not sure if there's solid ground above or below me, but there is water nearby.
