The easiest solution would be to simply move all other "On start of layout" events out of the "Game Engine Pausable" group.
Or you can investigate why this group becomes deactivated when layout starts. It's hard to tell by these screenshots, but I'm guessing some event momentarily sets InGameMenu to 1.
Or if you are switching to this layout from some other layout, it's possible that this group is already deactivated when layout starts. Add this to your event #1, it will tell you if the group is active on startup or not:
Is group "Game Engine Pausable" active -> Browser Log "Group Game Engine Pausable IS ACTIVE"
