Unreal Engine 5.0.3 crashes when I try to import my voxel

[tempaccountforissue]

After I press import or import all, Unreal Engine crashes and returns this error:

Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:C:\Program Files\Epic Games\UE_5.0\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 691] Array index out of bounds: -1 from an array of size 256
