W3 Total Cache screws up my website on mobile

Hi team,

I am raising this topic after trying to fix the issue myself for about a week. I have read the web and nothing seems to help.
I had installed and configured W3 Total Cache for website load optimization. Things worked well till the next morning I found that my website is screwed up. I immediately uninstalled the plugin and deleetd folders as per recommendations on Google. It fixed the website on laptop, but responsiveness on mobile is gone. The home page sliders, the font, style everything is screwed up. I checked it on iPhone and Android and the issue is same.
Can you please help me understand a bit about the problem and the way to fix it.
