Dear Joomlart Support,
I have the latest Joomla (4.2.5) installed and updated to PHP 8.1.13. As a result, before installing the latest T4 Page Builder (2.0.5) the following error on the page was shown.

After installing the latest T4 Page Builder (2.0.5) the following error on the page is shown, in the front end, and there is no way to access the site.

The problem is just with the update of the T4 Page Builder. The accompanying T4 builder article intergration plg 2.0.4. and T4 builder plugin 1.1.1 updates just resulted in the same error before installing the latest T4 Page Builder (2.0.5), after they were installed and the home page being refreshed.
The same issue is also on my localhost. Could you please determine what the problem is and provide a solution to this critical error. Did this problem not occur on your own server(s) before the latest updates were released?
Regards,
Mr B
