The object became invisible in game mode

My BP_road suddenly became invisible in game mode. At the same time, shadows and collision work well … When I press play, the road disappears and only the shadow from it remains, the collision also works … in the outline editor, the visibility icon becomes off.
please help me understand what’s going on. If i use this blueprint again, everything works as it should… the problem is only with this particular road that I already drew

Help me please ((
