WordPress 5.6 broke my ability to create posts.

Immediately after upgrading to version 5.6, when I create/edit a post either the settings tab doesn't work or the settings column is off screen to the right and inaccessible unless I take my browser zoom down to 80% (and then I still can't get to lower items in settings).
Also, after an update or a save draft, an attempt to return to the dashboard is met with the leave page warning that usually only happens when a change is made w/o saving or updating.
I downgraded back to 5.3.3 as this was reliable for me.
