For an error like this, first try just refreshing the dashboard and see if you still get the issue (maybe also try a different table/dashboard see if the issue is specific to that one). If you still have the problem, check the Adobe status page (status.adobe.com) to see if there are any current issues impacting workspace, that could be the cause of the problem.
If there is nothing on the status page and you are still getting the issue, you will likely need to reach out to customer support for help with the issue, it isn't something that we can diagnose here.
