I Have this same problem on two projects with Enfold theme:

First one:
Your current Enfold Theme Version Number is 6.0.6
Your PHP version: 8.4.4

Second one:
Your current Enfold Theme Version Number is 6.0.6
Your PHP version: 8.0.30

Problem apeears after update WP from 6.7.2 to 6.8.

Temporarily I change option i theme options:
From: Use Block Editor
To: Use Classic Editor

This problem is only with pages with signature: Advanced Layout Builder.
Without this block editor works properly (on WP 8.2)

How to repait it?
