Your words were correct, the problem was not with LSC, the problem was with another plugin (WP Content Copy Protection & No Right Click)
I stopped it and now the site is working
The plugin was reloading the page twice, so there was a problem
Thanks

Well understood
I see that the speed of my site has become faster after this
But there are problems for Google

like:

And the site takes a very long time to be archived in Google and appear in the search results
