Starting yesterday I noticed issues with some surveys on the Survey123 website, where I cannot get the Data page to load, I have encountered this on Chrome and Edge. The issue seems tied to surveys I have had issues with due to having a null geopoint question related to these bugs:
BUG-000147659: The stakeholder or results view layer created from the ArcGIS Survey123 Collaborate tab generated a duplicate table in ArcGIS Online if the survey is using a hosted table.
BUG-000146472: The submission fails when publishing a survey with multiple geopoint, geotrace, or geoshape questions, where the first geometry question has bind::esri:fieldType of null, which creates a hosted table instead of a hosted feature layer.
I've also gone over experiencing issues with just the form panel not loading on the Data page before and the extra tables here: Results View Contains Additional Tables compared t... - Esri Community but it seems the issue has escalated..
