Comment (by tomdb):

 == Reproduction Report
 This report validates that the issue can be reproduced.

 === Environment
 - OS: Win10
 - Web Server: no idea, it's a managed wordpress environment
 - PHP: no idea
 - WordPress: 6.5.2
 - Browser: Chrome, Edge, FireFox, all updated to latest version
 - Theme: Extendable
 - Active Plugins: see attachment of May 3

 === Actual Results
 - all list item content blocks display on every page of our production
 site displays "unexpected or invalid content" error in preview mode. The
 actual page displays correctly. Adding a new test page behaves the same:
 add content and save -> no errors. Reload page, same invalid content
 errors

 === Additional Notes
 - Issue not present on our development instance, running 6.3.2 with the
 same theme and plugins active.
