Getting Error 500 code

I’m having issues with your plugin on 2 sites. One I’m developing and one that I maintain. I can’t save anything in Elementor with your plugin enabled, it throws an error 500 code in the Elementor editor.
I’m using OceanWP (updated on one site, not the other) & Elementor Pro. Neither site has caching. One site is using IThemes Security, the other has no security plugin.
After disabling all the plugins, it was narrowed down to Dynamic Conditions.
The console is telling me that admin-ajax is returning a status of 500. That disappears when I disable your plugin.

I can grant admin access on the site I’m developing if you’d like to take a look at the issue?
