Dynamo 2.1 and Revit 2020 Crash

Hi all,

I could use some advice. So, while I tried to install Iris package my Revit crashed. Now I am unable to start Dynamo from within Revit.

Logs after crashed state this:

Dynamo log started 2021-08-18 12:44:51Z
2021-08-18 12:44:51Z :
2021-08-18 12:44:52Z : Dynamo – Build
2021-08-18 12:44:53Z : Duplicate migration type registered for SunPathDirection
2021-08-18 12:44:53Z : Dynamo will use the package manager server at : https://www.dynamopackages.com

Not sure what can be done. Anybody has some idea what to do?


Funny, but the solution was to just find Iris package in C:\Users%User\AppData\Roaming\Dynamo\Dynamo Revit\2.1\packages and delete it (allow showing of hidden files to ensure access to AppData if its maybe hidden like on my business laptop).

However, can somebody explain this behaviour?
