Magento 2.3.3 PayPal problem while checkout

Overwrite to: app/design/frontend/{your theme}/{theme name}/Magento_Checkout/web/js/action/select-payment-method.js

New:

 define([
    '../model/quote'
], function (quote) {
    'use strict';

    return function (paymentMethod) {
        /*if (paymentMethod) {
            paymentMethod.__disableTmpl = {
                title: true
            };
        }*/
        quote.paymentMethod(paymentMethod);
    };
});

Then do the compilation, then it will work.
