@KUNGERMOoN The stack trace actually only says this is originating from accessibility stuff without further specifics. The one time I managed to replicate this in debug mode some time ago wasn't more informative and usually rare. It doesn't seem to be an error in the app. And seems to be a fairly common unresolved issue with ListViews in StackOverflow. I will hide the views from accessibility as this method appears to be invoked from/for and this seems to be the only possible solution

Thanks!
