Love it or hate it, the Gutenberg Block Editor is here to stay. Personally I am not a fan. If you fall into this same category and want to disable the editor from loading up in your WordPress install then just add this block of code to your theme’s functions.php file.

//* Disable Gutenberg Block Editor *//

add_filter("use_block_editor_for_post_type", "disable_gutenberg_editor");
function disable_gutenberg_editor()
{
return false;
}
