Current code in TryCreateTransferScope (use thread_local as cache to avoid creating transfer scope) may have random failure which cause this CI failure (hangs as timeout, segfault as crash). By simply comment out it (i.e. don't use cache; always create "new_scope"), we won't run into any error anymore. We trial with several times to enable/disable this cache and proved no issue occur when cache is disabled.
