#Developer's Note Recently, an app running with arm64 on an x86_64 emulator system has identified symptoms of stopping or terminating on the initial blank screen. This issue will be fixed through a later version update. For LD Player or Nox, if both arm 32bit and arm 64bit exist, arm 32bit is running first, and Bluestacks can configure its priority.
