Magento 2

Error ‘TypeError: $(…).filter(…).collapse is not a function’ (in admin/backend > dev-tools console)

So you upgraded your site to 2.4.4.
Then you set your site to production mode.
After you login to admin you will see that the tabs are not working in the configurations and the settings is not saved.
You look in the console section of the dev-tools of the browser it has ‘TypeError: $(…).filter(…).collapse is not a function’ in theme.js section. Given below is the temporary fix which worked for me.
