Hi,
Thanks for reaching Q&A forum.
But please understand the only the topics listed in the homepage will be supported in Q&A forum and for your questions, we are unable to advise further since our remote desktop service forum is mainly focusing on discussion and technical advice for remote session or RDS deployment.
Thanks for your understanding and if any more assistance needed regarding RDS in the future, please feel free to reach us.
In addition, if this problem is more urgent for you I still recommend that you open a case to Microsoft for further professional help.

Hope this helps and please help to accept as Answer if the response is useful.
Best Regards,
Carl
