Dear Solgae,
Maybe we can have an SR for discussing this issue more further.
Meanwhile, could you allow me to ask an additional test on your local mac?
You can try to remove all files in the folder below and then give it a try again.
/Applications/VMware\ Horizon\ View\ Client.app/Contents/PlugIns/PCoIPVMView.bundle/Contents/MacOS/pcoip/vchan_plugins/
Thanks,
Jack
