magento / magento2

Sometimes e.g. after the weekend, we suddenly can't login into the admin area / backend of our shop, since installing this security patch: https://helpx.adobe.com/security/products/magento/apsb24-18.html

We need to delete our cookies to be able to login again.

Error:

Argument #1 ($datetime) must be of type string, null given in /vendor/magento/module-security/Model/AdminSessionInfo.php:136

magento2/app/code/Magento/Security/Model/AdminSessionInfo.php

Line 136 in 9721cc2

$lastUpdatedTime = strtotime($lastUpdatedTime);

This is how it used to be in 2.4-develop:

    $lastUpdatedTime = $lastUpdatedTime === null ? 0 : strtotime($lastUpdatedTime);

I don't have information on how to reproduce this.
