Sounds extension related then.

[ayoubkhan558]

I have synced same extensions which I was syncing with VS code stable. The problem occurs when I save files, Now it does not write undefined, it formats file unexpectedly.

[ayoubkhan558]

when I tried "Disable Configuration" or "Disable Extensions" now its fine, no problem.

Here is VS code profile https://insiders.vscode.dev/profile/github/5c9838e10757b14525fa50a78c7f78a3
