Are you destroying an object while calling OpenLevel?

No destroy object is called in begin play of a random actor

Could you show some code? Is the random actor itself destroyed or another object? Is your code trying to access the object after Destroy has been called? Errors like these pop up when objects that are marked for garbage collection still exist (because the GC hasn’t run yet) and some other part of code tries to access them.
