Please take a try to change the Data row limit for Non-delegable queries to 500, save and close your app, then re-open your app to check if the issue is solved.
In addition, please also take a try to refresh your data source within your app or remove the data source and re-add it within your app, then check if the issue still exists.
If the issue still exists, please take a try to enable/turn on the "Render in classic mode" option within Advanced Settings of App settings (App settings-> Advanced Settings-> "Render in classic mode" option), then check if the issue is solved.
