SAS® Studio might crash with "The application has encountered a serious error and must be reloaded"


The SAS Studio application might crash while you work with flows on the canvas.

As a result, the following message might be displayed on a blue background page:

“The application has encountered a serious error and must be reloaded” error followed by a link that says “Copy the full error to clipboard” and a Reload button.

Starting in SAS® Studio 2025.09 and later, the full error copied from clipboard is as follows:

TypeError: Cannot read properties of undefined (reading 'stepId')

Or, in only SAS Studio 2025.09, the full error copied from clipboard is as follows:

TypeError: Cannot read properties of undefined (reading 'name')

If you click the Reload button, the SAS Studio interface is re-displayed, but the changes to the content following your latest Save action could be lost.

This issue is rare, and the triggering actions are not consistently replicable.
