Master Slider PHP 7.2 Errors

My client’s website is hosted on WP Engine and they are switching to PHP 7.2 this week.

I installed the updated version of Master Slider Version 2.25.4 but the slider does not load on the home page and it breaks the rest of the page.

I need this fixed ASAP or my client’s website will not display correctly.
