Start by reproducing the crash at https://www.bakeryswap.org/#/launchpad in Chrome 121 on Windows 10, with the reported wallet extension context. Inspect the interaction between the compiled main.e94a7365.chunk.js code and injected.js; no source file or test is identified in the report. Done means the launchpad no longer throws this error in the reported setup.
