Microsoft released out-of-band non-security updates for Windows 10 Versions 1909 and 2004 as well as versions 1803 and 1809 for enterprise/education. The purpose of the updates is to fix the issue causing blue screens (BSOD) when printing to network printers with Type 3 printer drivers. The issue showed up after installing the March 2021 cumulative updates.
Because the updates are optional, they are not available via Windows update. However, if you have been affected by this issue, the updates can be downloaded manually from the Microsoft Catalog:
