Thanks @jacob.small

I removed my pyRevit (4.6.12) add-in from Revit and that did the trick.

While doing that I also found 3 packages in my 1.3x Packages folder that were made for 2.0 and removed them as well.

Forgot to add the sweet little graph @jacob.small shared with me to be able to check what version of Dynamo the custom packages I had installed were built on. It runs in Dynamo 2.0

[What Package Engine.dyn](https://forum.dynamobim.com/uploads/short-url/wjNFHbZtZHjlIsV7pW2WIguGMhs.dyn) (14.1 KB)

Thanks for your help!
