The mobile do not respond after few second on browsing

#1
something strange caused by Lite speed Caching plugin on mobile only. not the APP just regular browsing on the mobile. I am using the Buddy Boss theme for the course learn dash. so now on mobile only,
After few seconds on browsing the site on the mobile, the site
is not responding at all, just like frozen. the mobile Doesn't recognize the touch on my phone.
I tested it with other phones. it's the same. When I deactivated the Litespeed plugin, it kept going fine, with no issue. do you know what is wrong and what is causing this? it might one the feature that I need to deactivate it. but which one.
let us keep in mind that I am using the Lite speed on some other sites and all is fine. But Buddy Boss, is a heavy social network theme https://www.buddyboss.com/themes/

thank you
