Hi! I’m Charlotte, here to help you with the Openbank app crashing on your Windows device. To get started, could you tell me a bit more about when the app crashes? For example, does it crash right after opening? Or does it happen during a specific action? Also, have you tried any troubleshooting steps already?

Meanwhile, I’ll suggest some straightforward steps tailored for your Windows 10 environment to stabilize the app:

1. Restart your computer: This can clear temporary glitches.

2. Check for app updates: Make sure your Openbank app is the latest version available.

3. Repair or reset the app:
- Go to Settings > Apps > Apps & features.
- Find Openbank, click on it, then click 'Advanced options.'
- Under 'Reset,' try 'Repair' first. If the issue persists, try 'Reset' to restore defaults. (This won’t delete your data but will reset app settings.)

4. Check for Windows updates: Sometimes app crashes relate to system updates.

5. Close other programs: Running many programs at once can affect app performance.

If the app still crashes after these steps, let me know any error messages you see or specific actions triggering crashes. Then I can guide you deeper or suggest next steps.

Are you satisfied with this initial guidance?
