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

• VS Code Version: 1.66.1, 1.66.2
• OS Version: Ubuntu 20.04.4

So the issue I'm having is as an extension developer (ckolkman.vscode-postgres).

I've had users report an issue that I have tracked back down to vscode - I can confirm the issue on the above versions, but don't know the full extent on other os versions. (Borvik/vscode-postgres#196)

The error being received is: "Input is not valid base64-encoded data."

I've tracked this down to getting the secret from secret storage (https://code.visualstudio.com/api/references/vscode-api#SecretStorage).

I use the SecretStorage api to securely store credentials used by my extension. The api docs don't seem to indicate a change - but something appears to have changed (whether by design and the docs need to change, or by introducing a bug).

The issue does not appear to affect vscode 1.66.0 - reverting to that version allows it to work.

I do not know whether it affects whether it affects storing secrets - but can confirm on getting secrets.

Steps to Reproduce (with referenced extension - so far):

1. In vscode 1.66.0 - with extension, create a db connection with pwd to store creds (without pwd won't use store creds so it won't use the SecretStorage)
2. Upgrade vscode
3. Try to view the connection explorer and it will error when attempting to pull the secret from storage.
