    Follow these steps on Windows 11 to fix WhatsApp (Microsoft Store app) issues related to Microsoft.WindowsAppRuntime / MRM.dll:

    1. Close and reopen WhatsApp
      • Close the WhatsApp window using the X in the upper-right corner.
      • Wait a few seconds, then open WhatsApp again from Start.
    2. Make sure Windows 11 is fully updated
      • Select Start > Settings > Windows Update > Check for updates.
      • Install all available updates and restart the PC if prompted.
      • This is important because Windows App Runtime and MRM-related fixes are delivered via Windows Update.
    3. Update Microsoft Store and all Store apps
      • Open Microsoft Store from Start.
      • Go to Library > Get updates.
      • Let it install all available updates, including Microsoft Store itself and WhatsApp.
    4. Repair or reset WhatsApp
      • Go to Settings > Apps > Installed apps.
      • Find WhatsApp in the list and select Advanced options.
      • First choose Repair and test the app.
      • If the issue persists, return to the same page and select Reset (this may sign out of the app and clear local data for it).
    5. Reinstall WhatsApp from Microsoft Store
      • In Settings > Apps > Installed apps, select Uninstall for WhatsApp.
      • Open Microsoft Store, go to Library, find WhatsApp, and select Install.
    6. If Windows App (Windows 365 app) or other Store apps also crash
      • Crashes related to urlmon.dll or runtime components are often fixed by installing the latest Windows Updates before launching the app again.
      • Ensure all cumulative and optional quality updates are installed via Windows Update.

    If, after all of the above, Store apps in general still crash or fail, perform a broader Store/apps repair using the guidance for fixing Microsoft Store apps on Windows 11 (update Windows, update Store, repair/reset apps, and reinstall from Store as needed).
