Hello,
Firstly you should optimize your images because they are toooo heavy of some -> https://prnt.sc/C60yvBFm8iqi (1st of them is almost 1mb).
Also, your slider images are too heavy as well https://prnt.sc/6a1IpKa7b16U (128kb and 196kb) – keep in mind that they are loading almost at once page start to load because they are placed at the top on page content.
