Appstream2.0 build issue

Hi

I ran the image builder and created a new image (AppStream-WinServer2022-12-11-2023) Then I uploaded the vendor application and installed it using the built in Administrator account. I ran the application with the built in Admin account and it work. No issues detected.

Then tried the "Image Assistant" and added the vendor application. I then switched user to "Template User". I tried running my program directly as "Template User" (not using the "Image Assistant") and it work. No issues.

I start "Image Assistant" and see the application icon, (using Template User account) and run the application and nothing happen. It do not open the application.

Event Viewer give two errors .NET Runtime Event ID 1026

I can run the application using Administrator, Template User and Test User accounts. Using the "Image Assistant" to switch between accounts.

The problem is when I use the "Image Assistant" on either Template User and Test User account and try to start the Application by clicking on the application icon. It give me those two errors above in the Event log.

I am stuck on STEP 3 in the appstream guide since the "Image Assistant" cant run the program https://docs.aws.amazon.com/appstream2/latest/developerguide/tutorial-image-builder.html

In short the application is working on all three accounts if I start the application from Windows. The Application do not work executing inside the "Image Assistant" using Template User and Test User account.

I have one user account in the USER POOL and one image. I do not have anything else in AWS since I started using AWS this week.
