Command line --incognito no longer works

the command line switch --incognito no longer works in windows 10. have deleted and remade shortcut several times but it no longer works.

right clicking on menu icon and selecting new inprivate window also no longer works.

the only way to open an inprivate window is to first open a regular brave window and then open inprivate from that window’s menu. I only use inprivate mode therefore this is very annoying extra process.

Please help with new instructions for shortcut that will work. Thanks!
