vscode: Extension host keeps crashing on Big Sur

• VSCode Version: 1.52.1
• OS Version: MacOS 11.0.1

Steps to Reproduce:

1. Use VS code normally
2. Extension host crashes every half an hour or so

Does this issue occur when all extensions are disabled?: Yes

Hello all,

I’ve searched through the issues and this problems seems to pop up quite often, but it seems like each time it’s a bit different to my problem. My extension host keeps crashing often enough to interrupt development.

When I look at the developer tools, I get the same error message in the console: Error: No authentication provider 'microsoft' is currently registered.

Based on the error it seems like the problem is in the settings sync feature. Because of that, I tried all I could to reset the settings sync, but it didn’t seem to flush out the bug.

What I’ve tried so far:

• disabling all extensions
• uninstalling and reinstalling vs code
• using the insiders build
• signing out/in from/to settings sync
• removing the saved token in my keychain and logging in to settings sync again

I had a look at the settings sync logs and found this error logged:

However, this happened a while before the extension host crashed.

I’d greatly appreciate some help on this one, as it’s been bugging me for a few months now. I can’t find the issue anymore but someone had a similar story that was supposed to be resolved in version 1.51.1. Unfortunately I’m still having the issue. I’d be more than happy to provide any more information needed.

Thanks a lot for your help
