I'm here to guide you in performing some troubleshooting steps to resolve this unexpected behavior, @Grandpa Rome 3.

Let's start fixing this unexpected behavior by making sure that your QuickBooks software is updated to the latest version. This ensures that the program displays the latest features and resolve issues such as crashing updating your default statement email template. Here's how:

1. Open the QuickBooks drop-down menu.
2. Select Check for QuickBooks Updates.
3. On the prompt window, click Install Update.
4. Hit Install and Relaunch.

If the issue persists, you can run the Verify and Rebuild Utility tool. It is a built-in QuickBooks tool that can auto-detect and auto-resolve data-related issues within your company file. Then, the Rebuild tool will self-resolve it. Here's how:

1. Click File.
2. Choose Utilities.
3. Select Verify Data.
4. If a problem is detected:
   1. Go to File.
   2. Select Utilities. 
   3. Choose Rebuild Data.
   4. Run the Verify Data from step 1 one more time.
   5. If it still fails, restore a backup or contact technical support.

Once completed, let's make sure to reboot your device to ensure that all components are updated. You can read through this article for more detailed instructions about fixing issues when using QuickBooks: Troubleshoot Crash Catcher.
