Failed to read tasks file at {path}

Error message

Failed to read tasks file at {path}

What it means

While validating an extension's language directory, reading the tasks file (tasks.json) from disk failed. This is an I/O error wrapper: the file path exists in the directory listing but std::fs::read returned an error such as permission denied or a broken symlink; {path} names the offending file.
