Empty Woocommerce cart when page is loaded - php

Question

Im using Woocommerce with Astra theme and I'm trying to add a function that clears the user's cart every time the page is reloaded, even for logged users. I've already tried many solutions I found here but no one of them work.
Im using a plugin called "Woocommerce assinaturas" (Brazilian name) which is used to prevent non-member users from accessing the pages and somehow it is conflicting with any code I add in the "functions.php" file from my theme...
So what i need is: a code snippet (that is not 10 years old like most others I found here) that empty the user's cart every time the page is reloaded and doesnt conflict with the plugin im using.
Would be glad if I could manage to do the plugin function without it.
The code im trying to add to "functions.php":
add_action( 'template_redirect', 'custom_empty_cart' );
function custom_empty_cart() {
if ( ! ( is_cart() || is_checkout() ) && ! WC()->cart->is_empty() ) {
WC()->cart->wc_empty_cart( true );
}
The error:
Uncaught TypeError: array_reverse(): Argument #1 ($array) must be of type array, bool given in wp-content/plugins/woocommerce-assinaturas/woocommerce-assinaturas.php:978
