error

Is it and object that is actually used in that scene ?

  • first steps would be to:
    Check the build / cook log to see if this elements show up with a warning or anything
    Check it’s references, and resave the elements ( the one causing issue too ) and retry ?

edit after a small search: What can cause objects to break disregard for GC assumptions? - #4 by Steve.Martin
maybe you try to prload somme assets too soon durring the engine initialisation process ?
