PaperGroupedSpriteComponent->UpdateInstanceTransform couse editor to crash

Hello everyone! I find a little issue when using PaperGroupedSpriteComponent->UpdateInstanceTransform(…)

That cause editor to crash with reason:
Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\Build++UE4\Sync\Engine\Source\Runtime\Core\Public\Containers/Array.h] [Line: 611] Array index out of bounds: 26 from an array of size 0

But when I check array size and it has 59 elements, so there no reason really “out of bounds”.

The same problem was found in answerhub : https://answers.unrealengine.com/que…edspritec.html
But its doesn’t get the answer for me how to fix that. Also tried to find issue in Issues tab, but I didn’t get anything for that.
