91-95: Minor async library nit – addConfigureAwait(false)
DeserializeAsyncis library/infra code and not UI-context bound; usingConfigureAwait(false)avoids incidental capturing of a synchronization context:-var t = await MemoryPackSerializer.DeserializeAsync<T>(stream); +var t = await MemoryPackSerializer.DeserializeAsync<T>(stream) + .ConfigureAwait(false);Small but standard for low-level libs.

Resolve #3716.
When reading file stream, we need to wrap it with try-catch sentence.
