Google Penalty! with this plugins

After I installed the plugins and configured it according to THIS VIDEO!! (LiteSpeed Cache Settings Tutorial 2023 | Step-by-step Setup Guide YOUTUBE), after a day my ranking for the company started to drop from page 1 to page 5 in google this plugins started to index all kinds of non-existent pages from the server and I had 400 errors a day 404, the robot changed my txt and then Google penalized me because Google webmaster could no longer cope, the speed increased enormously from 10 seconds at 1 second but I ruined the raking, the traffic and the google position with their crawer!! so from my side it has a score of 1, I invested 25,000 euros in the site and a plow made by non-experts ruined it!!! this is my opinion.
