All Queries tracing in DAX Studio returns error after run

[Camill88]

Hi, I need to monitor perfomance in my PBI report. I open PBI Desktop, create new blank page, then run DAX Studio from ribon. Next I run All Queries, go back to PBI and go to final report page. All Queries trace starts but after a while an error apperas in logs:

This CollectionView type does not support changes to its own SourceCollection from a thread other than Dispatcher

I closed and open PBI again do clear the ceach and repeted the process. Same again. Have you ever encountered such an issue and how to sove it?

Encountering this error message is generally a sign that the thread is in an unsafe environment, which can lead to threading issues, since UI-bound collections can only be updated from the UI thread.

Take a look at the BindingOperations.EnableCollectionSynchronization and read this topic: Using BindingOperations.EnableCollectionSynchronization.

Enables a CollectionView object to participate in synchronized access to a collection that is used on multiple threads.
