FlaUILibrary Close Application by Name keyword gives "Application is not attached"

For context, I use FlaUILibrary to interact with a desktop application I’m testing, which I open using the Windows Search keyword from the RPA.Windows library, and close it with the Close Application by Name keyword as part of my teardown.

This worked previously, but last week IT had to completely wipe and reimage my computer and ever since then, the keyword errors out with “Application is not attached”. The rest of the test works perfectly, interacting with the application as expected. For one test I opened up a secondary program and closed it with the same command, and it errors out now when I try to close it too. Has anyone seen this before? I’ve gotten around it for now by using Close Window, but it would be a lot more convenient to be able to use Close Application by Name.
