Slider Revolution issue on JS optimization

Hello World,
I am using Malgre theme for my website and the main slider on my home page is a Slider revolution slider.
I am working on optimization of my website. But on using Async or Defer JS or Combine or Minify JS, the width of slider automatically gets reduced to 50% and there is no such option to fix it other than revert the changes and delete the plugins.

The slider width is reduced only in the user view (logged out users). When logged into the website, the slider is of full width.

I am attaching the screenshot link here

After – https://cityandtalent.com/wp-content/uploads/2022/07/Screenshot-2022-07-24-at-14.42.06.png

My GTMetrix score is very bad and need help to improve it by JS optimization.

Looking forward on receiving your help.

Thanks
