Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused.
There was a Windows client update released today that has a fix for smart card redirection, can you please check and see if that helps.
Here are the release details of windows desktop client.
Also, make sure that the SmartCard Driver is present on the host machine. Not the reader driver but the smart card driver itself. This will result in no SC being found after attempting redirection.
