Sharing Tools display blank window or crash

Hello everybody

we currently get some issue with ou Remote Desktop Server Windows 2016, when clicking on sharing tools in the top right of Acrobat Reader nothings happened, sometimes a blank menu is displayed or an error message appear, we try a full uninstall/reinstall, cleaning with Adobe Acrobat Cleaning Tool, %appdata%\Adobe removal, reconfiguration of mail client settings in Preferences, nothing seems to work.

Thank you for your help
