bug after core module update

[Pannox]

Good evening everyone, I try to find some support here, out of nowhere my site with prestashop 1.7.5.2 stable for years no longer allows me to access the backend after a simply update of module core, the 500 error in debug mode is this:

(1/1) ServiceNotFoundException
You have requested a non-existent service "PrestaShopBundle\Controller\Admin\Sell\Order\OrderController".

in ContainerBuilder.php line 1056
at ContainerBuilder->getDefinition('PrestaShopBundle\\Controller\\Admin\\Sell\\Order\\OrderController')
in DecoratorServicePass.php line 56
at DecoratorServicePass->process(object(ContainerBuilder))
in Compiler.php line 141
at Compiler->compile(object(ContainerBuilder))
in ContainerBuilder.php line 788

at Kernel->handle(object(Request), 1, false)
in index.php line 88

it must be a simple thing because the frontend works and upgrading to 1.7.8 everything starts again, I tried to clear cache and the like but to no avail, can anyone advise me something? thank you

did you make a back up before clicking on the core update?

[Pannox]

no, for core update I mean the system modules that are usually updated without any errors from the module manager they are usually harmless

Before any update or change a back up should be made. One click and you don't have a shop any more.
