Project base point clip removed in revit 2020.2
Accepted solution
It was removed because it (clip) is technically irrelevant. We could not really move a project by moving it clipped. The PBP can only change/provide an alternate "local coordinate system", one that a spot coordinate annotation can report on.
If you find this difficult to believe...Create a simple model, export to DWG using Project. Then move the PBP clipped and repeat to a new file using Project. Xref both together into another DWG using the WCS origin. They land in exactly the same place.
Now export the first and second file using Shared Coordinates and repeat the Xref process...the second file lands in a different location.

Relocate Project. Nothing has actually changed in how it works...just reflects the reality of the PBP not really "doing anything" to the project's origin while clipped.

Yep, it is only ever un-clipped...which is what it was before but implied otherwise, which was just plain confusing.

The clip is gone...won't be visible anymore. If the PBP is not at the Internal Origin then it will be used by a Spot Coordinate Annotation as the origin of a Local Coordinate System, apart from the Internal Origin, like before when it was moved "unclipped". If the PBP is at the Internal Origin then a Spot Coordinate assigned to Internal Origin or Project Base Point will report the same values, relative to origin.
Clipping or unclipping the PBP in the past didn't do anything, the action itself. It was only relevant when the PBP was moved, it mattered which state the clip was in during the move.
The trouble with moving it clipped in the past is that when a project has its Survey Coordinate System configured the move of the PBP messed up that configuration.

Can you right click on the Project Base Point and choose Move to Startup Location? Does it move? Where is it relative to the new Internal Origin icon? Where is the Survey Point?

Revit 2020 files don't go through an upgrade process...they just open in 2020.2. That's why the internal origin shows up in them...no upgrade means no intervention to go through and turn of the new sub-category they've added. Part of the upgrade process from earlier version is a specific task to turn it off. That doesn't resolve your issue tho...
Which icon is your model close to, the Project Base Point or the Survey Point? If near the PBP and Internal Origin icons you shouldn't need to move the PBP at all. Just export to Navisworks using the Shared Coordinate system. If near the Survey Point then that means the model is actually very far from the internal origin.
If you can post the file somewhere for me to look at it offline I can do that... Send me a private message with a link to a location to do it...if you want to. I can tell you what I find.

Mike shared the model with me. It is modelled very very far from the internal origin of the project, in the image below the model is located at the Survey Point. The model elements display as distorted which is a symptom as well. He was able to export to NWC via Shared Coordinates. To resolve the distance issue however it will be necessary to move it there. I did attempt briefly to bind the model but it generated errors that wouldn't allow it to finish. I don't know why without digging into it much deeper first.
