404 error for all pages on my wordpress website

Hey Support, I have been using the lite speed for a longer time, Now there is one issue with my website. When I set my permalink to post then all my pages and posts go to 404 pages I don't know why. Based on the post id, the page is open, but based on the slug, all the pages are not open. Also if you change the language it shows the 404 error. I don't know why. For reference I attached one screenshot please have a look as well. The site is in production. If you provide me the quick help that will be great.
