Opening dynamo keeps crashing Revit (2023)

Hello,

I didn’t use dynamo for some time, but today I wanted to start using it again because of a school project.
However everytime I open my revit file and then want to launch Dynamo, my whole Revit just crashes and I how to force shut it down. What can cause this problem and how can I solve it?
I already updated Revit to the newest version that exists however this did not solve the probem.
I’m working in Revit 2023.1

Thanks in advance

Seems like an add-in conflict, or a missing update.

  1. Close Revit and restart your CPU.
  2. Install any missing updates to Revit.
  3. Disable all Revit add-ins
  4. Rename the DynamoSetttings.xml and packages directory found in %appdata%/dynamo/Dynamo Revit/2.xx/ where xx is the Dynamo build you’re currently using (ie: udpated Revit 2022 would be 2.16). This will prevent any customizations to your package paths and any pre-loaded packages to not load.
  5. Launch Revit, and start a blank project from no template (select none in the drop down), and set the units to imperial
  6. Launch Dynamo and open your graph.

If the issue persists check your Revit journal for add-ins which weren’t disabled (search for vendor; only Autodesk, adsk, or some variation thereof should be present). If nothing was missed post the .dyn, your dynamo log file, and your Revit journal.

If the issue doesn’t persist restart again, undo the renaming of the settings and package path (you’ll have to delete the new versions), and repeat steps 3 and 4. If the issue still doesn’t re-occur we can confirm it’s an add-in. If the issue does re-occur you can start checking your installed packages in small groups until you identify the issue.

If it’s narrowed down to an add-in, confirm you’re using the latest version of all add-ins. Then restart Revit and disable in small groups until the issue no longer persists.

Hello,

I tried doing your steps, however this did not solve the problem.
I tried opening dynamo through Civil3D however this also didn’t work.
This makes me think that the problem is Dynamo and not the main program (Revit or Civil3D).
Is there a way to repair or reïnstall Dynamo on it’s own?

No - a repair requires reinstallation of Revit and Dynamo. If it is blocked in both Revit and civil 3D this indicates an issue with your infrastructure. Give Dynamo Sandbox a try and see if that is also broken.

That said, one of the final if statements was to post your Revit journal and the associated Dynamo log. Alternatively you can reach out to Autodesk support via the accounts portal at manage.autodesk.com.

Does it matter what I rename the files to at step 3?

I came to the conclusion that it does open if I wait for 30 minutes, however it works very slow.
Whenever I place a node I have to wait for 2 to 3 minutes to make it stop “not working” again.
What could solve this?

Restart the CPU as a first step.

Post your Revit journal, Dynamo log , and Dynamo settings file if it continues.

Where can I find my Revit journal, dynamo log and dynamo settings?
