Numbers keeps crashing

Hello kaniere,

Welcome to the Apple Support Communities. It's understandable to rely on apps like Numbers, and we'll be happy to help.

You've done a few great steps already. Try the remaining ones here: If an app on your Mac stops responding, closes unexpectedly, or won’t open

If you're still having issues, reach out to Apple Support directly: Get Support

Thanks, and enjoy your day!

Unfortunately, the fixes that work for some do not work for all. So far we have these three ideas, two of which you mentioned. If those fail, a fourth is to contact Apple Support directly.

1. Reboot (done you said)
2. Delete the app and reinstall fresh from App Store (done you said)
3. Log out of iCloud then log back in
