Reference

Microsoft requires security vendors to sign binaries using ACS. As a result, applying a minimal Microsoft Windows update based on the version of Windows is required. Therefore, customers who do not have the minimum OS build/patch of Microsoft Windows after February 18, 2023 may encounter the following errors:
