Help! My Game is so glitchy it is Unplayable!

My Game, The Wasteland, was a really good and advanced survival Game That had a extremely large Map, Various different menus and a lot of coding. Yet everything was fine until I added a huge amount of dark grey panels in Backdrop when it started to crash! Please Help! I deleted All grey panels and a lot more irrelevant stuff in game and still does not work!

BTW it cannot be size of Map, I have done bigger in other games! Check it out:

@“The Kodex” I think the biggest issue is having logic in all the stone level objects. That’s going to be pretty expensive to run, try removing it and see if that fixes your issue.
