Welcome to the QuickBooks Community, @Bradford Landscape Solutions.

I've checked your concern and find out that there is an on-going investigation about QuickBooks Desktop (QBDT) freezes when printing or emailing a transaction. 

As a workaround, you may perform the troubleshooting steps released by Microsoft: KB4567512. Let's make sure that you're able to download the latest windows update. Then, before sending emails or printing invoices, you'll need to reboot your PC after downloading the updates. 

I know that you've already contacted our support team. However, I highly suggest reaching out to them to add you to the list of affected users. Your account will be linked to INV-47379 and you'll be able to receive updates on this issue via email. 

Additionally, I've attached here a helpful article that outlines the instructions to set up Webmail or Outlook when sending invoices or reports in QBDT: Connect your email to QuickBooks Desktop. 

Fill me in if you have other QuickBooks concerns. I'll be around to help you. Take care always.
