wordfence security نصب

I had a problem with the WordPress dashboard after installing the Wordfence Security plugin. I need to say that I installed this plugin for the following reasons. The site has been attacked by bots and Japanese messages, all of which are visible in Search Console and Google Search. The site’s comments are full of links with Japanese titles. I delete them every day, but they still exist. The home page does not come up in Google Search, but there is no problem and it is indexed. The Fushgah link comes as the home page and displays Japanese ads! Even some of the site link titles have changed and are in Japanese… Now I can’t log in to the dashboard to delete the Wordfence Security plugin. What is the problem? Has a bot prevented me from logging in and activating this plugin?
