UE4 crashes when applying a ground tile

Unreal Engine crashes when I try to apply a ground tile material in my project (the meshe does not matter).

Step to reproduce: apply a ground tile
Frequency: always

Unreal Engine freezes and all my computer freezes after that.

Hi cypaubr

Can you please include detailed repro steps along with including the call stack from the crash, the project logs, and your DxDiag please?

Thank you!
