Hello! I see you're having trouble exporting your video in Blurrr Music Video Editor because the app kicks you out or crashes. Let's try to get this sorted out.

To better assist you, could you tell me:
- Are you using the Blurrr video editor on your Windows device's WebKit browser, or is it an app?
- When exactly does the crash happen? Right after clicking export or at some other point?
- Have you tried exporting with different project settings, like lower resolution or different formats?

Meanwhile, I can offer some common troubleshooting steps for export-related crashes:

1. Check for Updates: Make sure your Blurrr Music Video Editor is updated to the latest version, as updates often fix bugs causing crashes.

2. Reduce Export Quality or Format: Sometimes high export settings or certain formats overload the system. Try exporting at a lower resolution or a more common format like MP4.

3. Clear Cache/Temporary Files: If the editor stores cache, clearing it can solve stability issues.

4. Close Other Applications: Ensure other heavy apps are closed to free up memory and processing power.

5. Reboot Your Device: A simple restart can clear temporary glitches that cause crashes.

6. Check Project Size and Complexity: Very long or complex projects could cause crashes during export.

If you’ve already tried these or the problem persists, I can help guide you through checking advanced export settings or look for known issues specific to Windows 10 WebKit browsing environments.

Would you mind providing a little more info about your setup or trying these steps first? That way, I can give you the most effective help.
