@mplusb I’m running into the same issue on a basically clean install of WordPress 6.1.1 using the default WordPress themes.
The exact error message is:
Uncaught TypeError: Cannot set properties of undefined (setting 'display') at HTMLDocument.<anonymous> (readmore.min.js?ver=3.0.2:1:1286)
This issue only occurs when enabling the “Show html content.” option in a view.
I can send you a link in private to the website where the issue occurs if you’d like. But this should be easily reproducable.
