It seems you're experiencing an issue with the Microsoft Word app where it opens blank instead of allowing you to access Azure Virtual Desktop (AVD) for your SPSS needs. This issue may be related to several known problems when launching applications within AVD.

1. Blank Screens on Login: There are numerous reports from users who have encountered blank screens or freezing when trying to log in to AVD. This can result in either just a black screen or a screen that displays as "Securing Remote Connection" with no further progress. You might want to explore the discussion on black screens and login freezes for potential troubleshooting tips.

2. Application Launch Issues: Sometimes, applications fail to launch altogether, or you may not receive necessary pop-up notifications when trying to access them through AVD. This can cause frustration when trying to get to your desktop environment. You can read more about this in the resource on troubleshooting application launch issues here.

3. Community Reports: Additional discussions from users can provide valuable insights into common issues associated with AVD, such as frequent blank screens after logging in to a Windows 10 Enterprise for Virtual Desktop machine. You can view a related community post about this issue here.

4. Potential Fixes: There’s also a post discussing a scenario where applications display as blank icons in the taskbar when running in a Virtual Desktop Infrastructure (VDI). Understanding this problem could offer some parallels to your situation. More information on that can be found here.

Given these points, your best course of action may include checking your network connection, ensuring you have the latest updates for both the AVD and Microsoft Word app, and possibly reaching out to Microsoft support if these general troubleshooting steps do not resolve the issue.
