I am experiencing the same error on new instances created after 3:00 PM today. On the instance I had opened earlier, everything continued to work correctly. I also add that text pasted using Ctrl+V becomes corrupted. impossible to work!!

Had to disable auto updates too, settings.json:

{
    "alwaysThinkingEnabled": true,
    "env": {
        "DISABLE_AUTOUPDATER": "1"
    }
}
