Why is this happening?
how can i fix it?

thanks.

An easy but temporary fix, is to enable windows mixed reality.

Takashi.Suzuki:
This issue will be raised by loading WindowsMixedRealityPlugin at PostEngineInit phase. Normally it will be loaded at PostConfigInit.
You can set EnableByDefault true in WindowsMixedRealityPlugin.uplugin to fix it temporarily.

Now the biggest problem for me, is that when creating geometry collection the editor crashes… someone knows something about it?
