Root causes:

[2023-12-28T16:45:32.530+05:30][INFO ][plugins.screenshotting.chromium] Browser executable: C:\Program Files (x86)\Elastic-Stack\kibana-8.11.3\node_modules\@kbn\screenshotting-plugin\chromium\chrome-win\chrome.exe
In order to get help faster, please make sure to clearly state your problem in the summary.
Now to back to the issue:
security_exception: missing authentication credentials for REST request [/_nodes?filter_path=nodes.*.version%2Cnodes.*.http.publish_address%2Cnodes.*.ip]
First I would double check you can access Elasticsearch instance with credentials you set in kibana.yml
curl --user <your_username> -X GET "http://<your_es_host>:<your_es_port>/?pretty"
You can also check the similar issue and its troubleshooting.
Best, Dima
