Virtual app/desktop session launches with Citrix Workspace app 2305 for Windows might sporadically fail. This may result in session launches silently quitting, session disconnects with a gray screen, or session launches failing with an error message ‘SSL Error 27: No local security certificates could be loaded.’

Installing Citrix Workspace App 2305.1 will resolve this issue. This latest version is available via auto-update as well as the downloads page  for manual installation.
 

Note:  this version is based on TLS 1.2. Support for TLS 1.3 will be introduced in a future version.

Problem Cause

Citrix Workspace App might encounter random virtual desktop session launch failures on some Windows 10 machines with TLS 1.3 enabled due to memory related conflicts.
