Unable to access Shop Page?

Hi there,
I am using PS v5.7.6.9 and can access the Admin panel, but shop is not accessible.

I have inspected the generated log file and it contains, this information as given below

[13-May-2021 11:09:07 US/Eastern] PHP Fatal error:  Uncaught Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: The service "PrestaShop\Module\PrestashopFacebook\Factory\PsApiClientFactory" has a dependency on a non-existent service "PrestaShop\PsAccountsInstaller\Installer\Facade\PsAccounts". in /home/nikpaul/public_html/shop/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Compiler/CheckExceptionOnInvalidReferenceBehaviorPass.php:31

I will appreciate any assistance to get out of this mess, without compromising the data.
