Hi there! I see that Splice keeps crashing for you after exporting one video, and that’s definitely something we want to get sorted out for you. To help me assist you better, could you tell me if the app crashes immediately after starting the export, or does it happen right after finishing the export? Also, is this happening with all your projects or just one specific video?

Meanwhile, here are some steps that usually help with Splice crashing issues on Windows devices:

1. Restart your computer: Sometimes a simple reboot clears temporary glitches.
2. Check for updates: Make sure both Windows 10 and the Splice app itself are fully up to date. Updates often fix bugs that cause crashes.
3. Verify storage space: Ensure you have enough free disk space since exporting requires storage.
4. Clear cache and temp files related to Splice: If possible, locate the temp or cache folder for Splice and clear its contents. This can fix corrupted files causing crashes.
5. Try a new project: Create and export a very simple project (just a short clip) to see if exporting works without crashes. This helps isolate whether it's related to the project file.
6. Check folder permissions: If you’ve moved your Splice folder or changed its location recently, restore or reassign permissions for Splice to read/write there.

If you’ve already tried these or the issue persists, I can help you with some advanced steps like resetting preferences or reinstalling the app completely.

Would you like me to guide you through any of these steps? And please let me know more about when exactly the crash happens!
