Extremely slow website

Hello.

I made a website for my collage, which was pretty fast in the begining but now it loads in around 30 seconds on mobile. I tryed to investigate the issue, but i could not fix it fully. If anyone has a hint what could help me increase the site’s speed, I would appreciate.

The website is a onepage { link is below }
I have 15 plugins enabled, which includes LiteSpeed Cache plugin, to optimize css, js, cache, lazyload etc. but it did not seem to help me. The server is definitely fine, and cloudflare settings too.

Thanks in advance.
