Quick answer: Unreal Blueprint async-load of soft object pointer leaving memory allocated after cancel? StreamableHandle reference retained even on cancel - explicitly Release.
Cancel loading; memory shows the asset still resident; loaded list shows the asset.
Release on cancel
Handle->ReleaseHandle();Frees both the handle and the asset reference. Memory reclaimed.
Or use weak references
TWeakObjectPtr; GC reclaims naturally. Doesn't require explicit release.
Audit handle lifetimes
Each FStreamableHandle is a reference. Lost references = leaks.
“Streamable handles are reference-counted. Cancel doesn't decrement.”
Build a SafeAsyncLoad helper that captures and releases handles. Misuse-resistant.
