Something happened after updating Dynamo to install some packages.  
I get this error message when I start Dynamo from inside Revit.

Now, these nodes stopped working.

Any suggestions?

If your referring to the code block, that is not my issue, it’s the two nodes on the right that report null but use to show the new asset and add to a material. The code block was fine before but still pushes what i need through.

I removed archi-lab and springsui and my error messages are gone.  
I reinstalled both springsui is ok but archi-lab is poping errors.
