Whenever I call NativeList.Add(), I am getting this exception. Anyone have any idea how this could happen?

Had the same and went nuts. But then I tried not creating those NativeLists inside the Job but before and pass them in via the struct & the error went away.

Edit:
Ok, somehow the fix did not work anymore today. Instead, today removing CompileSynchronously= True fixed it :confused:

Adding too many items can result in this error
