I'd like to share some details and solutions to help you fix the email issue. This behavior has something to do with the Windows and Microsoft upgrades they make from time-to-time. You'll want to check the system requirements for QuickBooks Desktop 2021 for more details.
Since you have updated your QuickBooks Desktop to the latest version, you can do the following options:
- Change the file type of your logo in QuickBooks from JPG to PNG, or edit the form template and un-check the Use Logo option to remove the logos
- Uninstall the KB4560960 update in Windows 10.
I've got this link for reference: QuickBooks Desktop for Windows freezes when trying to email or print.
If you're still getting the same result, we can reset your Intuit ID to refresh the settings within your company by following these steps:
