Updated Drivers 
There is no 2021.2, so my guess 2021.1.2. The first step will be to update to the latest build of Revit, 2021.1.6 which was released 4 days ago. This should align with Dynamo 2.6.
If the issue still persists then we should check to ensure that Dynamo sees the geometry library. Try placing a point node and see what happens; if there is an error or warning let us know which.
If the point acts normal (other than not being displayed), provide your Dynamo log and Revit Journal and the larger community will help out as we can.
Thanks for the quick response Jacob,
Updated to 2021.1.6
Dynamo Core 2.6.1
Dynamo Revit 2.6.1
Still the same issue, No issues with dynamo seeing the geometry library as I can see geometry in the Revit window
Dynamo Log
Ok - so we can see that there is a geometry library in play (because the sphere.ByCenterPointRadius node didn’t return an error).
Do you have a Revit journal as well? The actual text document, not a screenshot, will be required - if the forum won’t let you upload post to another file share service (ie: dropbox, box, onedrive, googledrive, etc.) and I’ll have a look. It may also be better to submit a ticket to my colleagues in support so they can do a live screen share and active trouble shooting.
One other thing to try would be forcing both Revit and Dynamo to use your discrete graphics card, as this behavior used to be present when applications would default to the integrated card to save power.
Thanks again Jacob,
Revit is currently just using the NVIDIA graphics as shown below

There was an error creating a background preview in Dynamo. This could be due to a lack of graphics resources on your machine. See the log for more information.

Per your Dynamo log:
Looks like you will need to find Dynamo and force it to use the discrete card as well. You may have to add it to your card’s list of applications.
If after forcing the card you still don’t have graphics, create a ticket by logging into your Autodesk account at manage.autodesk.com, and submit a support request as you would with Revit or any other Autodesk product.
