Go to below js path :- app\design\frontend\Vendor_Name\Theme_Name\Magento_Ui\web\js\lib\core\collection.js

Line no :- 272 (find below line) var hasObsoleteComponents = items().length && !_.intersection(_elems, items()).length;

Just Replace function items just like below

var hasObsoleteComponents = items.length && !_.intersection(_elems, items).length;
