Description

In Windows 10 Update 1903, the "Microsoft-Windows-Kernel-Process" manifest was updated, and a new type "win:SID" was introduced.
This type is of variable length, it is a simple security identifier.

ProviderManifest.GetTypeForManifestTypeName returns null for "win:SID", and thus the parser doesn't parse anything after that field (so it misses the most important "ImageName" field).

Research direction

Start with ProviderManifest.GetTypeForManifestTypeName and the DynamicTraceEventParser path that handles manifest fields. Trace how an unknown win:SID field prevents subsequent fields from being parsed. Done means win:SID is recognized as a variable-length security identifier and parsing reaches the later ImageName field.
