Toggle font preview has stopped working. v11.0.0.1282
It is working fine here on Windows 10.
It’s working on another computer, both running Windows 11. How can I solve this?
Not solved by just uninstalling and reinstall. Solved by uninstalling database and cache as well.
In the screenshot in your other post I see the Preview column is hidden (or moved to the right), so no wonder you don’t see any previews 
You can right-click a column title to show or hide additional columns.
