I had the same issue time ago: > [@Array Length breaks editor](https://forums.unrealengine.com/t/array-length-breaks-editor/600895): > > Hello, I was developing using the Unreal Engine 5 editor and by some reason when I try to get the length of my array, the whole editor broke. Lucky me I was able to delete the bug element using CTRL + A and I got my editor working again. Really afraid of what will happen to someone that for some reason decides to forget the last part of the code that was added. Tried: Change the variable name ( Didn’t work) Change the variable type ( Didn’t work) Get Length in another part of the bluepri… My solution was to do a CTRL+A in the graph tab and delete all items and then rebuild them with what I remember. I hope it helps if you face the same issue again. --- _[View the full topic](https://forums.unrealengine.com/t/ue5-crashes-on-startup-after-crash-with-unhandled-exception-exception-access-violation-reading-address-crash-log/574276)._
