Some Core Nodes Not Working


I have been having an issue with Dynamo Version 1.3.3 where the “list” “create” and “watch” “create” nodes are not working.


The error message for the watch node is
“Warning: Whilst preparing to run, this node encountered a problem. Please talk to the creators of the node, and give them this message:
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index”
The error message for the “List Create” node is:
“Warning: Method ‘__CreateFunctionObject()’ not found”

I have not checked all the core nodes, however some others are working fine.

It is happening on all of the versions of Revit that I have installed (2019, 18, 17) , but it is not happening in Dynamo Sandbox or Dynamo Studio.

I have recently been installing nightly versions of Dynamo 2.1.0, so it could have something to do with that. As far as I have tested it 2.1.0 is working fine.

Any help would be appreciated.
