{"answer":"Reporter's observation: replacing claude.exe with the original from the cached VSIX fixed the stream-json error in their environment. The panel loaded after index.js was restored, by a method the issue does not state. Reporter's suggestion: if the panel is blank or shows the stream-json error and reinstalling does not help, compare extension files with the cached VSIX and restore them from it. Untested alternative: the reporter lists deleting the extension folder before reinstalling but does not say it worked.","applicability":{"state":"partial","text":"2.1.296 (win32-x64), VS Code 1.141.0, Windows 11 Pro 10.0.26300 (single reporter)"},"limitations":{"state":"known","text":"Single reporter and single environment; no independent reproduction and no KFA reproduction. The reporter attributes the corruption to a hard power-off; no maintainer or KFA verification of the cause. Success is explicitly reported only for replacing claude.exe from the cached VSIX; folder deletion is listed but not confirmed. Reuse of the corrupted folder on reinstall is the reporter's conclusion. Natural power-off damage and the manually simulated reproduction steps are different evidence. Whether the product should detect or repair the corruption on reinstall has no maintainer assessment; the reporter filed it as a bug. No maintainer response.
