Hello, folks.

Facing issue with Unity plugin is not able to locate/detect Houdini installation.

Platform : Mac Silicon M1 Max (2021 pro MacBook) - Mac OS 12.6.1
Houdini: 19.5.435
Unity: 2022.2.0b14 & 2021.3.13
Steps on how to reproduce the bug:

1. Install Unity plugin(.unitypackage) via Assets-Import Package - Custom Package...
2. Restart the Unity editor
3. HoudiniEngine menu appears in Unity:
4. Click Installation info:
"Unable to detect Houdini Engine installation" message

Houdini location is default, nothing moved.
It looks like the plugin detects correct path, cause when I try to open .hda file, this error is thrown in console:
>DllNotFoundException /Applications/Houdini/Houdini19.5.435/Frameworks/Houdini.framework/Versions/Current/Libraries/libHAPIL.dylib

And that path is correct, there is a file at that location.
Tried with LTS(2021) version of Unity, same result.
Nothing special in Editor.log


{ "name": "com.sidefx.houdiniengineforunity", "version": "19.5.435", "displayName": "Houdini Engine", "unity": "2019.1", "description": "Houdini Engine for Unity is a Unity plug-in that allows deep integration of Houdini technology into Unity through the use of Houdini Engine.", "documentationUrl": "https://www.sidefx.com/docs/unity/", "dependencies": {}, "author": { "name": "Side FX Software", "email": "support@sidefx.com", "url": "https://www.sidefx.com/" } }
When opening .hda files from plugin package getting "License could not be found" Error.
When trying to manually start Session, getting "Engine libraries not found" Error.
When running SessionSync dialog just hangs without error(in Houdini session started and port is open, accepting connections, tested with telnet).

SideFX responded that they logged a corresponding Unity issue as BUG #125545 in database.|
Lets just wait....
