While this issue is not found on KB4598298 nonsecurity preview release, which is also known as “C” release. It was released in February 2, 2021 which is distinct from the security release of January, known as “B” release.
Explaining the issue Microsoft said:
“This issue might occur when you try to activate the operating system with an OEM Activation 3.0 (OA3) Digital Product Key (DPK).”
