Undefined values on Minimize, Maximize and Close buttons window.

If minimize, maximize, and close buttons show undefined values, it may be due to missing assets or icon libraries, CSS issues like overridden styles or hidden content, UI framework misconfigurations, or JavaScript passing incorrect values. Ensure fonts and icons are properly loaded, and check for conflicts in CSS or JavaScript that could affect button rendering.

This error occurs for me too.
And the menus are still inaccessible, when clicking on the File, View and Help menu nothing opens.
