MacMail - Right column missing since last Catalina Update

In Mac Mail, I can no longer see the right viewing pane with the full email. I can only see the column with the email preview. I can change the width of the column. But not reveal the right pane. I see others posting about this problem, but can't find a solution that works. Is there a solution? I'm running Catalina 10.15.7

iMac 27″, macOS 10.15

Hover the cursor over the right edge of the Mail window until it changes to a left pointing arrow. Then click and drag to the left until the preview pane pops open. It doesn't slide open. You need to drag nearly the width of the Mail window.
