Disable Payment Gateway For Specific Shipping Method

Following Disable Payment Gateway For Specific Shipping Method On Checkout Only answer to my previous question, which:

Disables Payment Gateways ('cardgatecreditcard', 'cardgategiropay', 'cardgateideal', 'cardgatesofortbanking') When Specific Shipping Methods are Selected ('flat_rate', 'request_shipping_quote')

However, it seems that the last part is causing a conflict with the WooCommerce Home page:

add_filter( 'woocommerce_available_payment_gateways', 'filter_woocommerce_available_payment_gateways', 10, 1 );

function filter_woocommerce_available_payment_gateways( $available_gateways ) { 

    $gateways_to_disable = array( 'cardgatecreditcard', 'cardgategiropay', 'cardgateideal', 'cardgatesofortbanking' );
    $shipping_methods = array( 'flat_rate', 'request_shipping_quote' );
    $disable_gateways = false;

    // Check if we need to disable gateways
    foreach ( $shipping_methods as $shipping_method ) {
        if ( strpos( WC()->session->get( 'chosen_shipping_methods' )[0], $shipping_method ) !== false ) $disable_gateways = true;
    }
    
    // If so, disable the gateways
    if ( $disable_gateways ) {
        foreach ( $available_gateways as $id => $gateway ) {
            if ( in_array( $id, $gateways_to_disable ) ) {
                unset( $available_gateways[$id] );
            }
        }
    }
    return $available_gateways;
}

How do I go about troubleshooting this further?

This is the Fatal Error:

You need to restrict your code to only checkout page:

add_filter( 'woocommerce_available_payment_gateways', 'filter_woocommerce_available_payment_gateways' );
function filter_woocommerce_available_payment_gateways( $available_gateways ) { 
    if( is_checkout() && ! is_wc_endpoint_url() ) {
        $gateways_to_disable = array( 'cardgatecreditcard', 'cardgategiropay', 'cardgateideal', 'cardgatesofortbanking' );
        $shipping_methods    = array( 'flat_rate', 'request_shipping_quote' );
        $chosen_shipping     = WC()->session->get( 'chosen_shipping_methods' )[0];
        $disable_gateways    = false;
    
        // Check if we need to disable gateways
        foreach ( $shipping_methods as $shipping_method ) {
            if ( strpos( $chosen_shipping, $shipping_method ) !== false ) {
                $disable_gateways = true;
            }
        }
        
        // If so, disable the gateways
        if ( $disable_gateways ) {
            foreach ( $available_gateways as $payment_id => $gateway ) {
                if ( in_array( $payment_id, $gateways_to_disable ) ) {
                    unset( $available_gateways[$payment_id] );
                }
            }
        }
    }
    return $available_gateways;
}

It should work without making trouble in home page
