Play in Editor was stable after I created a cylinder and assigned a material that turns it red after a collision.
Since then I specified that the cylinder should only turn red on collision with a projectile from the player’s weapon and instructed it to patrol along the y axis.
I have tried to Play in Editor several times, resulting in an immediate crash all but two times. Each of the times it did not crash immediately, the cylinder disappeared immediately.

Any help would be greatly appreciated. This is the first project in the book “Blueprints Visual Scripting for Unreal Engine”
