Error during VS Code startup

[marcloydmirador]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.111.0 (user setup)
• OS Version: Windows 11 (Windows_NT x64 10.0.26200)

Commit: ce099c1
Date: 2026-03-06T23:06:10Z
Electron: 39.6.0
ElectronBuildId: 13330601
Chromium: 142.0.7444.265
Node.js: 22.22.0
V8: 14.2.231.22-electron.0

Steps to Reproduce:

1. Not sure it just randomly happened upon startup of the application
2. Maybe due to a pending Continue confirmation on Copilot chat when app was forced quit due to computer restarting?

/gifPlease what symptoms do you actually see in the product? Just an error notification or does chat return errors?

[vs-code-engineering]

Thanks for reporting this issue! Unfortunately, it's hard for us to understand what issue you're seeing. Please help us out by providing a screen recording showing exactly what isn't working as expected. While we can work with most standard formats, .gif files are preferred as they are displayed inline on GitHub. You may find https://gifcap.dev helpful as a browser-based gif recording tool.

If the issue depends on keyboard input, you can help us by enabling screencast mode for the recording (Developer: Toggle Screencast Mode in the command palette). Lastly, please attach this file via the GitHub web interface as emailed responses will strip files out from the issue.

Happy coding!

Hi @TylerLeonhardt,

There is not much happening; I just encountered the issue when I woke up my laptop and opened Visual Studio. During startup this popped out on the window. This happened for me multiple times.

Error serializing chat session for storage. The session will be lost if the window is closed. Please report this issue to the VS Code team:

@connor4312 I see you here:

vscode/src/vs/workbench/contrib/chat/common/model/chatSessionStore.ts

Line 374 in c2e1f3b

message: localize('chatSessionStore.writeError', 'Error serializing chat session for storage. The session will be lost if the window is closed. Please report this issue to the VS Code team:\n\n{0}', e.stack || toErrorMessage(e)),

so passing to you

[connor4312]

Update your VS Code for the fix.
