[SOLVED](5.3.5)UGUI crash when SyncDirtyElements

hi , we have the crash in UGUI when switch scene

it crash at:

CavasRenderer
IsActive
SyncDirtyElements

the issue last from 5.3.3 to 5.3.5, is there any method to avoid it?

as we, how can resolve it ?

now almost EVERYWHERE in 5.3.5p3…

problem solved:

I use Destroy(gameObject) to clear set of UI elements, and I changed to Destroy(gameObject,0.5f) the problems seems sloved.

There maybe a Unity’s bug in the CanvasRenderer logic.
