Can't use Dynamo 2.12 in Revit 2022

[Luffy11]

Hi everyone, when I open a node on Dynamo 2.12 in Revit 2022, it’s just empty as in the screenshot. Can anyone could help me to fix it? Thanks a lot.

Almost certainly a conflicting add-in. Disable all your Revit add-ins, and see if the issue persists.
