Closed as duplicate of #23609.
Current latest version of the plugin is 54. You should update the plugin. Maybe, a manual download of the plugin list is need under the Plugins Preferences prior to updating the plugins.

By the way, java version 18 is no LTS version. You might want to upgrade to version 21.

Sidenote: The sidewalks plugin is currently under active development. Feedback is greatly appreciated. Things may change, things may break.

If you encounter an issue, please update the plugin and see if you can reproduce.
