When opening a Power BI Desktop file, the app currently allows interaction (e.g., clicking visuals, opening Power Query) before all background processes like model hydration, query loading, and cache warming are finished. This can lead to laggy behavior, misleading previews, and even crashes—especially in large or complex models. I’d like to suggest a startup blocking mode that: Shows a clear “Loading…” screen when launching the app. Prevents any interaction (including visuals and Power Query) until: The semantic model is fully hydrated All queries are loaded and dependencies resolved Caches are warmed and ready Makes it clear and explicit when everything is done and the file is ready for user interactions or new development This would give users confidence that the environment is stable and ready for interaction, improving both usability and reliability—especially for developers and power users working with large datasets. Optional: This could be a toggle in settings, so users can choose between fast UI access or safe, fully-loaded startup.
