After upgrading to version 2026.1.211.462 of Telerik UI for ASP.NET AJAX , we are having a problem with the LoadSettings feature of the RadFilter. It is generating this error for any existing filters. We can delete and re-create filters and it seems to be find going forward but we have dozens of existing filters that will not load.
