Error-500 accessing the backend after upgrade to PS v8.1.1

[Obsidrian Drama]

Hi all!
I trust you're well.
After the last automatic upgrade to what I believe it's PS v8.1.1, accessing the backend throws an error-500.
The frontend seems to work fine, as long as I don't set the PHP version to something newer than 7.4...

The error:

ServiceNotFoundException

HTTP 500 Internal Server Error

The service "prestashop.adapter.news.circuit_breaker.settings" has a dependency on a non-existent service "prestashop.core.circuit_breaker.guzzle.cache_subscriber".

Stack trace can be found here: https://dpaste.org/ZX765 

Any ideas how to fix this and resume access to the backend?

Thanks a lot in advance!

I have the same error since upgrading to 8.1.1.

Here https://github.com/PrestaShop/PrestaShop/issues/30761 there's an active discussion on the same issue that seems to be occurring since some time ago with the 8.x versions ...

In this PR (https://github.com/PrestaShop/autoupgrade/pull/609) they propose to remove the file  

src/PrestaShopBundle/Resources/config/services/adapter/news.yml

When I do it and refresh the backend link, another error shows up:

Oops... looks like an unexpected error occurred.

It continues even after restoring the copy of the news.yml file... 

Suggestions? 

TIA!

The "stability" field was added to this table in Prestashop 8.0. 

That you get this error suggests that your update didn't finish correctly but crashed due to some bug. You need to go back to your old version.

As the Github post that Obsidrian Drama mentioned mentions the ps_accounts module as involved I suggest you try upgrading with the Github version of Prestashop as that doesn't contain this module.
