Solution: Check for and install the latest macOS updates through System Preferences.

FAQs

My Mac Mail app keeps crashing after the Mojave update, and I've tried restarting my Mac. What else can I do?
Restarting is a good first step, but if Mail is still crashing, try these: 1) Check for Mail updates in App Store. 2) Repair your Mailbox(es) by going to Mailbox > Repair Inbox. 3) Create a new user account to see if the issue persists (this helps determine if it's a system-wide or user-specific problem). If the problem only happens in your main user account, it might indicate a corrupted user profile. 4) If all else fails, reinstall macOS. Back up your data before doing this!
