Hey all,
I had this problem in windows 11 with UE 5.3 that I couldn’t find the option to start the project as standalone game from the right click menu when selecting the uproject. I don’t know if there is a solution to add this option to this menu. But there is an alternate way to achieve the same thing:
When you’re in the editor, click on the three horizontal dots next to the play-icon and then select “Standalone Game”. This will launch the game in the standalone mode and show “Steam”. Don’t forget to reset it to “Selected Viewport” when done.

Hope this helps.
