Just installed the following Windows Update:
as part of the bigger KB4457920 update.
However, after installing it, many .NET application that are running on the server start failing in different moments. When the applications fail, the following errors are logged in the Event Viewer and uninstalling the update is the only solution.
Every time the applications fail, these 3 errors are logged at the same time:

Since it's an update to prevent "remote code execution" it needs to be installed. Is there any re-configuration and/or code changes needed after the installation to prevent the issue?
Windows version: Window Server 2012 R2 Version 6.3.9600 -- .NET Version: 4.5.x
Note: I've installed all the pending updates and this happened:
- Installed Nov-2018 updates (KB4467242) successfully. KB4457920 failed. > Apps started failing.
- Reinstalled KB4457920 and it was failing. Uninstalling KB4457034 fixed the issue.
