Fatal Error on Single Product

Hi, I’m experiencing an error using a Child off the Neve Theme.
In my Shop (“Tienda”), I have a sidebar on the left. Visiting the general shop page is fine, but if I click any product, I get a fatal error. If I switch to any other theme, everything works fine. I got the debug here:

Fatal error: Uncaught Error: Too few arguments to function xlwcty::add_body_class(), 1 passed in /home/customer/www/aranysport.com/public_html/wp-includes/class-wp-hook.php on line 307 and exactly 2 expected
in /home/customer/www/aranysport.com/public_html/wp-content/plugins/woo-thank-you-page-nextmove-lite/includes/xlwcty-public.php on line 574
