From then the notebook UI can be rendered any more as we got tons of Text Editor errors.

@rebornix we are unable to repro the crash on both my machine as well as on @rzhao271 , can you attach the crash logs following the steps at https://github.com/microsoft/vscode/wiki/Native-Crash-Issues#creating-and-symbolicating-local-crash-reports. If you are unable to repro, check for existing reports from your previous runs at %APPDATA%\Code - Insiders\Crashpad\reports

This looks like a crash from native module used with the python/jupyter extension. We don't have any native modules from core that runs in the extension host which uses external array buffers.

@deepak1556 thanks for the info! Turned out to be a duplicate of microsoft/vscode-jupyter#10386. It's weird that the crash brought down the extension host and the notebook UI can't function properly. Will follow up in that issue.
