Create events.xml file

app/code/Vendor/Module/etc/events.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <event name="controller_action_predispatch">
        <observer name="customer_controller_action_predispatch_event" instance="Vendor\Module\Observer\ForceCustomerLoginObserver" />
    </event>
</config>

app/code/Vendor/Module/Observer/ForceCustomerLoginObserver.php

    <?php
    namespace Vendor\Module\Observer;

    use Magento\Framework\Event\ObserverInterface;

    class ForceCustomerLoginObserver implements ObserverInterface
    {
        /**
         * @var \Magento\Framework\App\Response\RedirectInterface
         */
        protected $redirect;

        /**
         * Customer session
         *
         * @var \Magento\Customer\Model\Session
         */
        protected $_customerSession;

        public function __construct(
            \Magento\Customer\Model\Session $customerSession,
            \Magento\Framework\App\Response\RedirectInterface $redirect

        ) {

            $this->_customerSession = $customerSession;
            $this->redirect = $redirect;

        }

        public function execute(\Magento\Framework\Event\Observer $observer)
        {
            $actionName = $observer->getEvent()->getRequest()->getFullActionName();

$controller = $observer->getControllerAction();

            if($actionName == 'catalog_product_view')
            {
                if(!$this->_customerSession->isLoggedIn()) {
                    $this->redirect->redirect($controller->getResponse(), 'customer/account/login');
                }
            }
        }
    }

After that don't forgot to clean cache !!

Override the layout catalog_product_view.xml and add a new custom block and phtml file.

Create a custom block file and add code for getting customer sessions, if the session exists continue otherwise redirect from it.

For adding custom block check that reference Add custom block and for getting customer session check reference Customer Session.

You can achieve the requirement by creating a module with following steps:

Step 1: Create registration.php under

app/code/STech/LoginProduct/registration.php

with below content:

<?php

\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'STech_LoginProduct',
    __DIR__
);

Step 2: Create module.xml under

app/code/STech/LoginProduct/etc/module.xml

with below content:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="STech_LoginProduct" setup_version="0.0.1">
        <sequence>
            <module name="Magento_Backend"/>
             <module name="Magento_Catalog"/>
            <module name="Magento_Customer"/>
        </sequence>
    </module>
</config>

Step 3: Create di.xml under

app/code/STech/LoginProduct/etc/frontend/di.xml

with below content:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Catalog\Controller\Product\View">
        <plugin disabled="false" name="STech_Plugin_Catalog_Controller_Product_View" sortOrder="10" type="STech\LoginProduct\Plugin\Catalog\Controller\Product\View"/>
    </type>
</config>

Step 4: Create View.php under

app/code/STech/LoginProduct/Plugin/Catalog/Controller/Product/View.php

with below content:

<?php
namespace STech\LoginProduct\Plugin\Catalog\Controller\Product;

class View
{
    protected $customerSession;

    protected $_urlInterface;

    public function __construct(
        \Magento\Customer\Model\Session $customerSession,
        \Magento\Framework\UrlInterface $urlInterface
    ){
        $this->customerSession = $customerSession;
        $this->_urlInterface = $urlInterface;
    }

    public function aroundExecute(
        \Magento\Catalog\Controller\Product\View $subject,
        \Closure $proceed
    ) {
        if (!$this->customerSession->isLoggedin()) {
            $this->customerSession->setAfterAuthUrl($this->_urlInterface->getCurrentUrl());
            $this->customerSession->authenticate();
        }

        return $proceed();
    }
}

Now run the below commands:

php bin/magento setup:upgrade

php bin/magento setup:di:compile

php bin/magento setup:static-content:deploy

Thats it!
