Hi Sankalp,
Have you tried this?
For the Vision lab stuck after code update: Try clearing your browser cache, switching browsers, or reconnecting. If it still won’t resume, contact lab support to reset your environment.
For the Document Intelligence lab “access denied” error: Ensure you’re logged into the correct Azure account, try restarting the lab, or logging out and back in. If it persists, reach out to lab support for access help.
