To update this thread, we believe we’ve narrowed down the issue to be a problem with selection groups, dynamic panels, and repeaters. The gist of the issue is if you have a widget that is in a selection group and is set to Selected by default, and that widget is in a dynamic panel within a repeater, then you’ll trigger the freeze if you have multiple states in the dynamic panel that also contain other widgets that are set to Selected by default and are in the same selection group as the first widget. QA is investigating this one and currently we don’t have a timeline for when this one is slotted for fixing, but the workarounds in the meantime would be to either not use dynamic panels (groups seem to work), or not have the Selected widgets in each state of the dynamic panel all be in the same selection group (or not all set to Selected by default). You can keep an eye on the release history thread for news on released fixes. Thank you!
