Reproducing the Issue
Login to the instance.
Access Homepage tile under concern.
Error displayed on Homepage as "Assertion failed: Config: There was at least one error".
The issue is attributed to changes made in the instance.
Changes were done in the datasets after the tile was initially created and saved and these changes haven't been picked up by the homepage tile.
Once a dataset configuration has been deleted, all Dashboards /tiles using this dataset should be modified.
Update the individual dashboards/tiles to point at the correct dataset group/modify the dataset group selection within the Dashboards in the Homepage.
You could also alternatively do a 'Save as' action to refresh the Dashboards with the latest setting to avoid a similar issue in future.
