Lay 10.6.2 + PHP 8.2: Fatal error when editing posts/pages

[smartin]

Hi Lay Support,
since updating earlier today to Lay Theme 10.6.2 on a Bitnami/Lightsail WordPress setup, I can access wp-admin, but opening any page/post in the editor crashes and shows “There has been a critical error on this website”.

Server details:
• PHP: 8.2.7
• Lay Theme: 10.6.2
• (Bitnami / AWS Lightsail stack)!!

Do you have any idea what might cause this?

Happy to provide more context if needed.

Many Thanks!
Martin

For now I rolled back to Laytheme 10.5.9 and it works again
