Error message

Source directory does not exist or could not be found: {sourceDirName}

What it means

Thrown by Themes.CopyThemeDirectory when sourceDirName does not exist. A DirectoryInfo is created for the path and `dir.Exists` is checked before any copy; a missing source yields DirectoryNotFoundException. This routine is used internally when scaffolding and updating themes, so a wrong source (often the bundled Default theme path) propagates upward.

Solutions

1. Verify the source directory exists with `Directory.Exists(sourceDirName)` before calling; log the resolved absolute path.
2. Ensure the Default theme template folder for the requested ApplicationMode is present under Paths.GetThemesPath(mode).
3. Re-deploy the Toolbox Templates/Themes tree so the Default source is available.
4. Pass absolute paths; avoid relying on CWD for theme template roots.

Example fix

// before
Themes.CopyThemeDirectory(@"Themes\Default", outDir, approved);

// after
var src = Path.Combine(Paths.GetThemesPath(mode), "Default");
if (!Directory.Exists(src))
    throw new DirectoryNotFoundException($"Source theme missing: {src}");
Themes.CopyThemeDirectory(src, outDir, approved);

if (!Directory.Exists(sourceDirName))
    throw new DirectoryNotFoundException($"Source theme directory not found: {sourceDirName}");

When it happens

Trigger: Calling CopyThemeDirectory with a sourceDirName that is misspelled, on a different drive, or not yet created. Internally: GenerateNewTheme copies from Paths.GetThemesPath(mode)/"Default"; if that Default theme folder is absent, this throws.

Common situations: Portable/extracted Toolbox lacking the Default theme templates; mode mismatch (requesting Fullscreen themes when only Desktop templates shipped); path case or separator issues on the Default theme source.
