Enabling Plugin causes fatal error and elementor widget panel is not loading

Hey,
I think this Plugin is eaxctly what we are looking for. We are trying to display a custom selection/query, that has been made with acf post field, with elementor. Unfortunately we are having troubles when enabling the plugin. Once it is enabled the front end says there is a fatal error and the elementor widget panel is not loading anymore. We already tried raising the memory limit, but that didnt help. Does anybody have an idea what could be causing that issue? Could the problem be an incompability with wordpress 6.0 or the Elementor Version 2.5.0?
Any hints to what might be causing this would be appreciated.
