Windows 10 v1903 Logoff issues

Question

Hello, 
 We are testing Windows 10 V1903. 
 When we logoff from the Windows 10 Desktop it goes to a Black screen and the computer is unresponsive, can't even ping the desktop. A hard reboot is necessary to get back in. At first I thought it was video card related but same thing happened on 4 different machines. When we uninstall the Sophos Endpoint, windows acts as it should and logging off is possible. 
 I have seen the memory issues with regards to V1903 but not this. Has this been reported and is it an issues with anyone else? 
 I have created a ticket. 
 Thanks again, 
 Mark

Has anyone tried the following: Global exclusions: https://cloud.sophos.com/manage/config/settings/scanning-exclusions 
 Add Exclusion of type "Exploit Mitigation (Windows)" Click "Application not listed?" Add in $system32\fontdrvhost.exe 
 and choose to not protect this application as per below: 
 
 Does this help? It would be worth checking that the version of HMPA installed has a build number (last 4 figures) is 1045 or later for this to work. This can be seen in Sophos Endpoint Self Help and in Central under the "Installed component versions" expandable link per device. Regards, Jak
