Optimising JS breaks a slider

PageSpeed Insights says that the render-blocking javascript file wp-includes/js/jquery/jquery.js is a big issue for my page speed. When I add it to the optimisation list I get about 76/100 and without I get around 60/100 for mobile.

However, when I optimise delivery of this file a slider on my homepage (made with Master Slider) doesn’t display at all. I’ve tried checking “Add try-catch wrapping?” but it still doesn’t display.

Is there a way to get it to work and optimise that file or should I try and switch my slider plugin?

Thanks!
