Hi akklex,

The same error has also been reported in this thread. If the suggested solution in the thread is not working, you might want to create a new workspace and create a new notebook there.

Hope this helps. If so, please give a Kudos 👍 and mark as Accepted Solution ✔️.

Hi akklex ,

Thank you for reaching out to the Fabric community. The error AzureNotebookRef has been disposed usually means that the Fabric notebook or Spark session is in an invalid state, and it’s not related to using a trial version.

Here are some workarounds you can try.

1. This issue sometimes occurs in specific browsers, especially Chrome. Try opening the notebook in Microsoft Edge using InPrivate mode, as many users have found this resolves the problem.

2. Clear the cookies and cache for app.fabric.microsoft.com in your browser settings, then sign out, close the browser, and reopen it. Afterward, try creating the notebook again to reset the session.

3. If possible, sign in with a different Microsoft account and create a notebook. Once successful, switch back to your original account. Some users have reported this resolves the issue.

Since you have the Diagnostic ID and timestamp, you can also submit a support ticket to Microsoft so they can check your tenant and link it to the known issue.
