Diagnosing TPM_E_NOCONTEXTSPACE

The result TPM_E_NOCONTEXTSPACE (0x80280063) means the TPM has no context-management space available for the requested resource.

Reproduce the same boundary

record loaded/saved TPM objects and sessions, context counts, owning process/service, and commands that fail to save or load context.
Preserve the first lower-level status, request ID, or object generation before retry/cleanup changes it.

release stale TPM resources or serialize usage through the owning service, then retry without increasing unrelated system memory. A new HRESULT afterward is evidence that execution crossed this boundary.
