I'm sure she'll try again and lay when she needs to. You said earlier that she got stressed out by the garbage bag visual barrier. What color was the garbage bag? If it's black, that could be the reason. Most of the time the can distinguish between living creatures and inanimate objects. If something is clearly inanimate, they won't be bothered by the color. If they think something may be alive, and hence communicating to them via color (the way chameleons communicate), then they will get stressed if something is black (stress colors) or some other random colors. And if the garbage bag isn't secured all the way and moving around a bit, then that can also stress them or give them the false idea that an inanimate object may be alive.
This is all just a theory based on my observations. And different chameleons respond to differently to different colors and to objects.
You could always try utilizing a different object to create a visual barrier such as corrugated plastic. It's cheap, rigid, and white. You could use a few screws to hold in place, some tape, or a couple of zip ties to secure it into place.
Or you can secure some fake plants to the outside of the screen to help block the view.
There are many alternatives out there for you to use if you like.
With that said, she's probably just testing the lay bin. She's most likely not abandoning her holes because she sees you. Just keep providing the care you have been giving her and she will most likely lay. You've got this!
