ms-python.python Webview is not loading on some systems.

[rchiodo]

• VSCode Version: 1.46.insiders
• OS Version: Mac

Steps to Reproduce:

1. Install python extension
2. Run command 'Create New Blank Jupyter Notebook'
3. Blank window appears 50% of the time (it should show a toolbar and a single cell).

See the discussion here (we can't reproduce in house):
https://github.com/microsoft/vscode-python/issues/11865#issuecomment-631911989

Does this issue occur when all extensions are disabled?: N/A

It looks like the webview is created but the extension HTML is never loaded. We thought this might have been issue: #89038 but it's not showing the same symptoms (resource load errors).

Do you have any guidance on how we might debug this?

Are users seeing this on the most recent VS Code insiders?

[rchiodo]

According to the user's comments, yes. See the linked issue: (https://github.com/microsoft/vscode-python/issues/11865)

We cannot repro in house though.

Specifically this comment where the user responded after I asked them to install the latest insiders:

Seems like the same issue as #98746

Can you please have the user test the next insiders build. The build includes a potential fix for this issue, but since I can't repo this I can't confirm

[rchiodo]

Will do, thanks.

[rchiodo]

I can confirm that this seems to fix the problem for those customers that were hitting the issue. Thanks.

Thanks for confirming. Closing as a duplicate of #98746 then
