Content and CSS sections are completely blank—no content is show, not even the editor window.
We rolled the PHP version back to 7 (from 8) and that seems to have fixed the issues. We still needed to restore a backup to recover the content in our Tab - it had completely disappeared (I checked the postmeta database table). We're now running 2.0.4.
