New critical bug with last update 10.1.2138.13

Hi,

Like usual, new update fix things, and brings new bugs...
But that new one is very critical !

Indeed since that last update released this week, we can no more perform remote assistance on already opened user sessions !
We can start a remote control on a computer and get to the windows logon prompt, but for already opened session (especially for ts servers), its not working anymore !
Either the error "unable to establish connection to guest agent", or the message that the remote session have been initiated, but the the browser doesn't open the remote window, nothing !
Tested with 30 clients with all distribution servers and agents up to date.
Tested with edhe, chrome, firefox. tested with colleagues.
All same issues.

That new update is a terrible nightmare !

For us desktopcentral is simply no more usuable !

A quick reaction is needed !
