I can't do anything with optimization.

I have the same problem, but the editor doesn't lag so much, but it still happens that it doesn't put one corridor or object. when you move quickly and place an object, the object may not be placed, unfortunately, it is better to put objects a little slower, or make sure that the music is so that your game does not freeze for 2 seconds when new music starts playing
