Uncaught type error on x-theme

Hi.
I’m using the plugin with the x-theme wordpress theme. When I activate the plugin the blog and portfolio pages stop working and in the console I get this error.

jquery-migrate.min.js?ver=3.3.2:2 Uncaught TypeError: Cannot read properties of undefined (reading 'length')
