May I get some Idea for this case?
hmm, what are the details of the crash? You might also want to open the issue here with the information filled out.
As the inputs are duplicating my guess goes towards the usage of a package in dyn 2.x which is made for dyn 1.3 and not updated yet
Great thoughts @Jonathan.Olesen!
However, @khaingwahhlaing58 is not in Dynamo 2.0.x and that node is OOTB. The duplicate port issue is for NodeModel nodes that have UI as well.
I recommend checking to see that you have sufficient RAM and C drive space, then restarting your computer, launch Dynamo and check the console for errors, and then attempt to recreate the crash from a new graph. If it crashes submit the issue to the github.
Thanks Jacob. Ok ready Now. Yes My C drive is almost full. I clean up the drive and installed dynamo2.0.2 again. Now ok ready. I am not the dynamo user yet. I just start to learn this software. Thanks for your suggestions.
