Standalone game crashes when opening world partition level

[Trent-Fellbootman]

Hi, I followed your tutorial and setup the plugin. I have a main menu level from which a world partition level will be opened on pressing a button. When I hit play standalone game in the level editor with the main menu level open, the game launches and displays the main menu screen successfully, when I click that button, the loading screen shows, after a brief period of time it enters the level and then immediately crashes with this error log:

Could you please examine what is going wrong?

Oh and if I just play in the selected viewport things work fine despite no loading screen showing up. From the error log it seems that the standalone game is trying to do something expected to be done in the editor, thus causing the crash?

Update: the bug disappears in packaged game, so it ain't really a malicious one

I have this issues too, sometimes
