Studio 19.10.6 - Exchange Autodiscover could not be located


recently I updated Studio from 19.10.4 to latest version. Afterwards, during the process execution, when i use Send Exchange Mail activity in Process.xaml, every time is thrown exception Autodiscover could not be located. Whats more, when I copy and use this same activity in Main.xaml or any other file, it is executed correctly. This behaviour could not be fixed by downgrade of mail activities. Also I tried to downgrade Studio to version 19.10.6 which is available at Cloud - still same error. Finally, I downgraded Studio back to 19.10.4 version, and activity is executed correctly again.

Do you have any solution? This issue is one of the reasons why I can not upgrade Studio.

Thank for any help
