Start by reproducing the crash at https://app.diffusion.fi/#/swap with the reported swap state, then trace the minified main chunk stack around the failing tokens access back to the TypeScript source. Done means this state no longer crashes the swap interface and the behavior is covered by an appropriate regression check.
