Fatal error opening routine

Sometimes when I try to open a Routine directly through Dynamo, a fatal error occurs and closes Revit.
For that not to happen I have to open the routine through the dynobrowser. What’s the explanation for that? Is it possible to solve?

Wich version (Revit & Dynamo) you are using?

Revit 2020 and Dynamo 2.3

It happened may be you added new package… But Fatal Error most of time happen because of Revit file .But i like to add here @jacob.small.

Might be a conflicting add-in, package, or an attempt to upgrade an old 1.x package to 2.x in bulk with dependencies also needing an upgrade. Dyno might get by any of those depending on how it works under the hood (I am not familiar with the inner workings of it).

Restart your CPU, open Revit and start a blank project, trigger the crash by launching Dynamo and then a problematic graph. Post the Revit journal and Dynamo log from that session.

Thanks! :slightly_smiling_face:
