Hi IgorBucheInikov,
Does one new unity project work with this nuget package normally? And according to this error, please check if the parameters are valid so that they can be passed into System.ComponentModel.ListSortDirection.
Besides, you could also try to remove bin and obj folders, then restore the nuget package and rebuild the project.
If they don't work, we suggest you could move to unity forum, maybe the community members could provide better suggestions for you.
Best Regards,
Dylan
