Would you mind translating that error message to English the best you can please?
Also, what version of Houdini are you using, exactly?
How did you install the Houdini Engine plugin for UE4?
Try removing this folder (the HoudiniEngine folder):
C:\Program Files (x86)\Epic Games\4.12\Engine\Plugins\Runtime\HoudiniEngine
And copying it back from:
C:\Program Files\Side Effects Software\Houdini 15.5.522\engine\unreal\4.12
– where you replace 15.5.522 with your version of Houdini.
