Hi Abhi,
How are you doing today? as per my understanding, this looks like a notebook state or browser session issue. As a temporary workaround, try opening notebooks in separate browser tabs, testing in incognito mode, or clearing the browser cache.
It may also help to share the browser name, workspace details, screen recording, and exact steps to reproduce the issue with Databricks Support. This will make it easier for the team to investigate.
Thanks, Brahma.
