The VST3 Synchron pinaos player doesn't appear. I have only a little window with the DAW frame and nothing inside.
The VST2 Synchron pinaos player is ok however.
This issue is observed with Reaper and with Cubase.
I have tried to reinstall the player with Vienna Assistant with no improvement.
Vienna Synchron Pianos.vst3 file is dated June 2022 and not December 2022 like its surrond version. The Vienna assistant hasn't updated it.
