While Windows 10 is preparing - installing Windows updates, it may happen that Pyramix MassCore crashes when starting playback.
If you press on the Windows Start button to shutdown / restart Windows, you can see "Update and Restart" / "Update and Shutdown"
Some updates may change resources that MassCore (RTX) is currently using and the system might become unstable.
It is highly recommended that MassCore users restart their system if a Windows update (even minor) was installed in the background.
Often this is noticeable when the Windows Start Menu indicates "Update and Reboot" or "Update and Shutdown". In such case do not continue your work but save and reboot.
