Remove data from mysql

Hi! I’ve created own snippet, but it has the wrong code (with error). When I’ve clicked saved then my whole website has crushed.

I see the error:

Fatal error: Uncaught Error: Call to a member function have_posts() on null in /home/users/www/public_html/wp-includes/query.php:895 Stack trace: #0 
/home/users/www/public_html/wp-content/plugins/insert-

The site is experiencing technical difficulties. Please check your site admin email inbox for instructions.

It disappears when I deactivate the plugin. I removed the plugin and install, but an error has appeared again. I would like to completely deactivate the plugin with all data (I see some data in MySQL).

How to achieve that?
