I hope you are well today and thank you for your questions.
You can disable each of autoptimize options one by one to find out which option is conflicting with Slider then contact autoptimize support to resolve the issue.
Also pagespeed insights still shows this. Am I missing something?
I can see in your shared screenshot that it says minified CSS file can be more optimised so also in this case autoptimize support can help you.
