Character not possesed when starting from command line or shortcut

Hello everyone

When I start my project using command line (batch file) or a shortcut command, the player character seems not to be possessed. It is not possible to input anything.

If I test the game from inside the editor in PIE mode, everything is OK

I have custom game mode, and character (actually just renamed from the FPS template) setup as per the attached files. I strongly suspect the problem comes from those, but I don’t know where to look for…

Any idea will be greatly appreciated !

best
