Research direction
Start by reproducing the crash at https://app.diffusion.fi/#/swap with the reported swap state and inspect the stacktrace from the generated main.fe3de569.chunk.js bundle. Trace the minified functions around the Array.sort and tokens access, then verify that the swap page no longer crashes for this state.
