Hi there! I understand that YNAB has crashed for you. Let's work together to figure this out.

Could you please share a bit more about what happened when it crashed? For example, were you in the middle of a specific task, or did it crash when you launched it? Knowing more will help me assist you better.

In the meantime, here are a few initial troubleshooting steps we can try:

1. Try a Different Browser or Private Window: Open YNAB in another browser or a private/incognito window. If it works there, it could be a browser issue or cache-related problem.

2. Clear Cache and Cookies: Sometimes cached data can cause issues. You can clear your cache and cookies in your browser settings.

3. Disable Extensions: If you have any browser extensions (like the YNAB Toolkit), try disabling them temporarily to see if YNAB runs properly without them.

4. Check YNAB Status: Sometimes, YNAB might have service outages. You can check the current status here.

Once you’ve tried these steps, let me know how it goes! If you need further help, I’m here for you.
