My unreal editor crashes a lot when I right click and mouse over stuff. It can be right clicking a folder in the Content Browser, or right clicking to add a Decorator or Service in a behavior tree, or trying to add an anim notify. It’s kinda random where the crash will happen, and if it will (it used to not be as frequent, but right now it happens very often).
Usually, when I restart the computer, the problem disappear momentarily and I can right click… but only for a couple hours or couple minutes. It really is making me impossible to use the editor.
When it crashes, I get the following error:
Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\Build++UE4+Release-4.18+Compile\Sync\Engine\Source\Runtime\Core\Public\Containers/Array.h] [Line: 610] Array index out of bounds: 0 from an array of size 0
