MA version 1.4.5.3 Causes Critical/Fatal Error

I just updated to the latest MA version 1.4.5.3 and now I get a critical/fatal error. I have a local WP install (via Desktopserver) with the NEVE theme (latest version), and the following plugins: NEVE Pro, Elementor free, contact form 7,edit author slug, revision control, themeisle companion.

Here’s the error message and stack call:
