I am creating an online store with WP and Woocommerce and when I choose a variable product and put a larger quantity in stock to see if the error messages work I get this error “/wp-admin/admin-ajax.php 500 (Internal Server Error)” and when I reload the page there if it shows me the message that there are not enough products, how can I solve it?

I tried updating the plugins and checking to see if another one was installed but no more plugins have been installed for weeks
