Hi,
I need some help.

I updated my Houdini so I can use Houdini Engine in Maya 2022.
Also, I instaled the Engine for Maya via the Houdini Engine Shelf in Houdini.
So far so good.
After I turn on the plug-in and restart Maya my Arnold plug-in is gone (missing from the plug-in list).
If I turn off the Houdini Engine plug-in and restart Maya, I have Arnold plug-in again (and now I can turn it on).

If I turn on the Houdini Engine plug-in (while I have the Arnold plug-in still turned on, and no Maya restart), I got both plug-ins, but the Houdini Engine is not working properly.
When I try to load an hda the loading never ends.

Do you have any idea what could be the problem?

note: I'm using Houdini and the Engine as well for years.

Thanks, D
