PHP upgrade fail

Hi – please help me – my host (Dreamhost) for my site (currently on Enfold 4.1.2 has failed an upgrade for PHP 8.2 – and they have identified the following error:

After careful investigation, I found that it seems your active theme: enfold may be the reason for the failure.
When doing a test via the backend. I noticed that the following error:

With that being said. I would recommend trying a different theme and then
attempt the upgrade. Or, perhaps have a developer or enfold theme
developers further check that error and see if they can provide an update
for PHP 8.2.
