On some occasions, unmanaged customizations to forms might prevent the setup to correctly configure the navbar section of entities.
You would see an error similar to this one, telling about a transition of an unmanaged solution being impossible.

The first step to solve this issue is to identify the causing entity.
You need to find the errortext highlighted in purple in the XML tree.

Follow the tree up till you find the formXML node.
The localized name will tell you which entity is failing.
You need to uncheck this entity from all locations in the configuration.
You can process all other entities as normal.
