Unable to load VRayForRhino.rhp plug-in: initialization failed

Hello, I try to install VRay, but I recieve this error: “Unable to load VRayForRhino.rhp plug-in: initialization failed.”
I tried VRay 6.26 and 6.25 build with the same result.
I have Rhino 8.12.24282.7001 and Windows 10 Pro 10.0.19045

Do you have any ideas what to do?
Thanks for your help.
