Please note that beta Unity versions are not supported since Unity may change things the next day, however I just try importing NodeCanvas from the Unity Asset store (package manager) on a new clean project of Unity 2022 Beta and there wasn’t any issues. Please note that once imported a message pops up by Unity to upgrade deprecated API within which I selected to do it.
Do you still get the same error you posted at the top on a new clean Unity 2022 project?
