I Have already check all my dynamo .dyn file through visual studio code.
Totally i have 12 .dyn file
This is one of the .dyn file i have, as you can see.
All the file HAS NOT Bindings EXCEPT the underlined file. Like your example below.
I have already turn off the preview element on all nodes, i was thinking so because maybe it taking the GPU or RAM to render. So i turned it off.
Hmm wondering whats caused the issue.
