Duo crashes on Windows when started from Citrix

[louis-brusco]

For the last two days Citrix will not load Duo from Workspace.  It tells me to run it or download it, which it is already done.  It worked fine on this PC before this.  There was a Windows update (2025-03 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5053598)) and since then it will not run.  I have uninstalled and reinstalled both Citrix Workspace and Duo Desktop (7.5.0.0).  When I am looking in Task Manager, Duo Desktop shows up briefly, sometimes showing as suspended, but immediately closes.  I have tried installing an older version of Duo - no improvement.  I have tried changing browsers and no improvement.  My laptop works with same company Citrix server and same network and logins.  Company IT cannot help because they technically can't support personal devices even though they do allow them.  Device registration with the company is fine.  Any other ideas to try?

I have tried to run Duo Desktop as Admin to see if I can enable Debugging like others have recommended but it will not load to let me get to a menu.

Thanks in advance for any help!  I wish Citrix would support Duo users instead of just the Admins...

We also released Duo Desktop 7.5.0 around the same time last week. Could you try installing the prior version to see if it also has the same issue? https://dl.duosecurity.com/DuoDesktop-7.4.0.msi

A few of our team members are running that Windows update without crashing, so it doesn't look like a general issue with that particular update to me. However from your description it does sound like the app is crashing. Could you find the latest Duo Desktop log file (found in `%LOCALAPPDATA%\DuoDesktop\Logs`) and also check in Event Viewer to see if Duo Desktop is generating an Application or System log with the crash info? And if you send that to me in a private message, I can take a look. Thanks!
