Any change or just pressing “Set as Default” in the project settings collision tab causes character example project to not spawn character and camera falls through the floor.
Steps to reproduce:
1: create new project in launcher, select 3rd person blueprint project
1b: run project, character spawns fine and all works good
2: after project created, click on Edit->Project Settings and select Engine->Collision
3: just press “set as Default”
4: Press Play to run project and the camera just falls through the floor and stops just below the floor.
5: character seems missing from outliner too.
Discovered when trying to add Projectile type to collision settings.
