A* Project not installing correctly, multiple errors

Hello guys. Im trying to install the package in my project but i get multiple errors.
I dont know where to even begin, but from what i’ve seen, most errors seem to be caused by “VersionedMonoBehaviour” being missing from namespaces.

Plus, when i install the package i dont receive the popup that notifies the user of the installation being succesful, like when i tried installing the package on an empty project.

What is VersionedMonoBehaviour and why is it causing so much trouble?

Any ideas? Thanks.

This is the error (the first and possibly the most important) as described by unity

Assets\AstarPathfindingProject\Core\AstarPath.cs(27,26): error CS0246: The type or namespace name ‘VersionedMonoBehaviour’ could not be found (are you missing a using directive or an assembly reference?)


Which version of Unity are you using? And which version of the package are you trying to install?
