Answer

Close Developer Studio, then delete the entire contents of its User Directory for that specific version (under your user profile's AppData\Roaming\DeveloperStudio\<version> folder), download a fresh installer from the Developer Portal, and reinstall. This clears out whatever partially-installed or corrupted module state caused the missing-module warnings, and a clean reinstall against an empty user directory resolves the startup issue.
