Research direction

Start by reproducing the crash on the /#/vote route using the reported URL, then trace the stack from static/js/main.b50380e6.chunk.js into static/js/4.806c3d88.chunk.js, focusing on the ABI decoding access at index 8. Done means identifying the malformed or unexpected decoded data and confirming that the vote page no longer crashes under the reported conditions.
