I finally got it. It’s probably your theme with an outdated version of Woocommerce conflicting with the new version so no payment methods are shown as there is a PHP error. Look inside your theme zip file and delete anything you find the same in the theme an woocommerce plugin.
P.S: In my theme it was wordpress.php and also a folder called wordpress with that doing the trick. Try changing the theme to default then follow my instructions.
Hope after reading this it gives you PROFIT?
