Hi ArjanFraaij ,

Thank you for reaching out to the Microsoft Community Forum.

 

Please check below things to fix the issue.

 

1. Restart the notebook kernel and re-run the cell. Try running the same notebook in a new session or workspace. Switch to High Concurrency sessions instead of Standard ones.

 

2. Increase timeout in Workspace Settings. Workspace Settings --> Data Engineering --> Spark Settings --> Jobs.

 

3. Clear browser cache and cookies. Use Microsoft Edge for best compatibility. Disable extensions that may block WebSocket connections.

 

4. Check with your admin to review the Spark job logs in the Fabric Admin portal and Capacity metrics at the time of failure.

      The base issue of sessions that won't start seems to be gone today
