A session security level is a setting that determines how secure a user's session is based on factors such as their login method, their IP address, their browser, or their device. Administrators can configure different session security levels for different user profiles and assign different actions or permissions to each session security level.
Multi-factor authentication (MFA) is a feature that requires users to verify their identity using two or more factors of authentication when they log in to Salesforce, such as their username and password plus a verification code or an app-generated token. MFA can enhance the security of user sessions and prevent unauthorized access.
If an administrator recently implemented MFA with a standard security level selected and is receiving cases that users are unable to log in, they should check the session security level required at login on the user profile. This setting determines what session security level users need to have when they log in based on their profile. If this setting is higher than the standard security level, users may not be able to log in with MFA alone and may need additional factors of authentication.

Data Categories are a way to organize and classify knowledge articles into a hierarchical structure based on topics or criteria. Data Categories can help service reps quickly narrow down the number of articles by filtering or browsing by category. Data Categories can also be used to control the visibility and access of articles for different users or roles.

A permission set is a collection of settings and permissions that give users access to various tools and functions in Salesforce. A permission set can be used to extend users' functional access without changing their profiles. You can assign permission sets to individual users or groups of users based on their business needs. In this case, you can create a permission set with Read access to the Government ID field on the custom object and assign it to the Institutional Team users who need access to this field via reports.

One possible reason for the changes to case routing is the difference in the order of execution between before save flow triggers and workflow rules. Before save flow triggers run before assignment rules, which means that any field updates made by the flow can affect how the assignment rules assign the case. Workflow rules run after assignment rules, which means that any field updates made by the workflow do not affect how the assignment rules assign the case. Therefore, replacing workflow rules with before save flow triggers can change the case routing logic.

To resolve the issue with the Process Builder, the administrator should do the following steps:
Review the Error Email for the Process Builder and rectify the issues. The error email contains information about what caused the error and how to fix it.
Deactivate the Process Builder in production. This will prevent further errors from occurring while the administrator fixes the Process Builder.
Fix the Process Builder in a sandbox and migrate the change to production. This will ensure that the Process Builder is tested and validated before deploying it to production.
