Start with the reported extension path, C:\users\\AppData\local\buster, and buster-client-log.txt, comparing the logs before and after reinstall. Request exact installation steps, the extension version, and browser console output to reproduce the manifest-loading error on Windows 11 with Chrome 120. No source files or tests are identified; done means the reproduced installation loads without the missing-or-unreadable manifest error.
