export-startlayout gives non readable output

Hello readers,

We have a server 2012R2 environment with 2 RDS servers and a Connection Broker.

When I try to export the Startdesktop (Export-StartLayout -Path "C:\Beheer\start_new.xml") -Path ", i get instead of a xml file an output in non readable format like:

When I ran the cmd, there was no error message.

A few years ago, the StartLayout was exported succesfully.

What I have tried so far:

- tried the export on different servers (RDS and non-RDS)

- tried the export with a different (domain) admin account

- tried the export with optie "-as bin"

I found only one other reference to this issue online, but unfortunately no solution: https://social.technet.microsoft.com/Forums/en-US/71e76f2a-2b40-466a-8046-fa191babfb9a/how-to-hide-additions-applications-from-windows-81-using-group-policy-server-win2k8-r2?forum=w8itprogeneral

Anyone an idea how to fix this?
