Hello !
For our project we need some features that are coming in Unity 2021.2. Everything works when upgrading to the latest beta, except Behavior Designer.
Basically we get this error at runtime and when opening any external behavior :
MissingMethodException: Method 'Cannot create an abstract class '{0}'..BehaviorDesigner.Runtime.SharedVariable' not found.
(I found a kind of similar issue in the forums but it wasn't the same problem origin)
I understand it's a beta version of Unity and not a top priority to fix before the stable version release, but maybe there is a simple workaround that exists ? ?
Thanks,
Daniel
P.S: Here's the complete error log:
