@akhil_baki_AP23110011494 If you want to restart without losing progress, please note that this will be done automatically once the Amazon AWS session is finished. It will take some hours, but then it will start a fresh new AWS session. Yet, your files in the vscode will remain the same.
Hey @akhil_baki_AP23110011494. In order to get a fresh version on the notebooks and other files, you need to delete them from the lab environment (or rename them if you want to keep them as reference), and then click on the Get latest version button (its above the Reboot option). Please keep in mind that if you don’t rename/delete the files, it won’t overwrite the existing ones, so that step is key.
