    Hi,

    Please try this:

    Press Windows+R keys on the keyboard, or Right-click Start on the Taskbar and choose Run.

    Type/Paste %localappdata%\Packages\Clipchamp.Clipchamp_yxz26nhyzhsrt

    Press Enter.

    Delete everything in the folder, including subfolders - ensure Clipchamp is closed beforehand.

    Restart the computer and verify if the problem goes away.

    I hope this information helps. If you have any more questions, don't hesitate to reach out.

    Try these steps in order:

    1. Open Clipchamp in the desktop app instead of the browser
      • On Windows 11, launch Clipchamp from the taskbar search or All Apps.
      • If it is not installed, install it from the Microsoft Store.
      • If it is already installed but has not been opened in some time, update it to the latest version first.
    2. Make sure the browser and Windows are fully updated
      • If using Clipchamp in a browser, use Microsoft Edge or Google Chrome.
      • Update the browser to the latest version.
      • Update Windows to the latest version.
    3. If using Edge, turn off protections that can block Clipchamp
      • Open Clipchamp in Edge.
      • Click Added security or the lock icon to the left of the address bar.
      • Find Tracking prevention for this site and turn it off.
      • Reload the page.
      • If needed, add the site to Edge’s allow list at edge://settings/privacy/trackingPreventionExceptions.
    4. If using Brave, allow fingerprinting temporarily
      • Click the lion icon to the right of the address bar.
      • Temporarily allow fingerprinting for Clipchamp.
    5. If the Clipchamp app will not sign in or open correctly, clear the local app cache
      • Press Windows + R.
      • Open: %localappdata%\Packages\Clipchamp.Clipchamp_yxz26nhyzhsrt\
      • Clear the contents of these folders:
        • AC
        • LocalState
        • LocalCache
      • Then try signing in again.
    6. If Clipchamp still will not open, reinstall it
      • Go to Settings > Apps > Installed apps.
      • Find Clipchamp.
      • Select the three dots > Uninstall.
      • Reinstall it from the Microsoft Store.

    The code 0x800b0001 is also shown in one Windows 7 installer case tied to update-signature validation, but the available Clipchamp guidance here does not provide a Windows 11-specific fix for that code itself. The supported Clipchamp actions are the app update/reinstall, browser update, Edge protection changes, and clearing the Clipchamp local cache.
