TypeError: undefined is not an object (evaluating 'this._observer.disconnect')

[RedNo7]

My Home Assistant version: 2023.5.1

Layout-card version (FROM BROWSER CONSOLE): 2.4.4

What I am doing: checking the logs

What I expected to happen: nothing - everything seems OK in my dashboards

What happened instead: n/a

Minimal steps to reproduce: not sure. I use this card everywhere. Looking for pointers to trace this log entry.

Error messages from the browser console: error from the logs (not sure what 'browser console is"
