Extension activation failed, run the 'Developer: Toggle Developer Tools' command for more information.

After vscode got its python insider's daily update(today), it cannot load the extension and displays what the title shows above.

Same problem here.

@rchiodo Is there any way to download an older version of the insider's channel? I need several of the upcoming features in my daily workflow.

[rchiodo]

I believe there's a 'stable' versus 'daily' setting. Not sure if that would change it though.

If you turn off the auto update, and then try going here, that might work too: https://dev.azure.com/ms/vscode-python/_build/results?buildId=29002

Upper right hand corner click on 'Artifacts' then scroll down to the VSIX.

I believe that build is working.

@DonJayamanne, @karrtikr, @ericsnowcurrently something since build 29002 has broken the extension loading.

I believe it was one of these 3 changes:

• https://github.com/Microsoft/vscode-python/commit/c513de793b6caa932e96cce27f57f42252e8b434
• https://github.com/Microsoft/vscode-python/commit/d92460be5b9944570ae24e51035b69956264864f
• https://github.com/Microsoft/vscode-python/commit/86d669e3906c533bb6f674b1745ce90389b8e75a

@rchiodo Thanks a lot! That build is indeed working. 🎉

However, "python.insidersChannel": "stable" is not recognized. Must be either "daily", "weekly" or "off". A "stable" setting that only updates to "stable" insiders would be cool, though.
