Dynamo closes directly after opening (Revit 25.1)

Hello!

I have the phenomenon that Dynamo (3.0) closes right after opening it from Revit 2025.1. What can you recommend me to get it working again? What data do you need to check the causes.

The thing is that not only one computer shows this behaviour, on 3 different computers Dynamo closes directly after opening. Reinstalling Revit to Revit 2025.0 did not help, or did I fail to uninstall anything?

If anyone has had the same problem, please post the link to the solution and thread.

Kind regards
Olaf

Best to contact Autodesk support directly via the accounts portal at manage.autodesk.com.

Be sure to restart the system, recreate the issue, force quit Revit, and gather the Dynamo log and Revit journal from the crashed session.
