Because of this topbar, your CLS is suffering.
To make sure of this, try disabling this topbar and checking again via Pagespeed.
You have very good metrics at Page Speed already.
Hope that helps you.
You don't have to disable the entire header. Most likely it is an announcement bar. If we are not mistaken, then it is configured in the theme settings. Theme->Customize or if you use the app, you can temporarily disable it.
