I have reinstalled Revit.
As per this topic and also, and as per notification in dynamo itself, I have removed addins from this folder:
C:\ProgramData\Autodesk\Revit\Addins\2022
I have uninstalled Diroots and Pyrevit.
After this there are no notifications in Dynamo, but Dynamo sees existing scripts like this
And I cant seem to add any nodes, Dynamo just freezes.
I have pasted my journal to chat gpt as per this comment
”Need the full journal to find out if there is an issue there. Best to restart the CPU, then launch Revit, start a new project from no template, launch Dynamo, quit dynamo, quit Revit, and then grab the journal and the log. if your system locks up entirely during the process force quit Revit and grab the journals and Dynamo log at that point.”
