PythonScript UI was broken to black

How Can I make my pythonscript UI in Dynamo normalize? because now I can not see the screen of PythonScript ,but it can work.

I guess the problem it that I tried to open dynamo when in pyRevit? So, copied this code below to my another script.

In addition, I have checked dynamo API from this discussion Dynamo API Documentation

Any suggestion is very appreciated, thanks in advance

@hctungBHP7B ,

hmmm… start a new python node. or restart dynamo, or restart your Computer… :wink:

@Draxl_Andreas Thank for your reply. After my test only restart my Revit or computer can make it, but my Revit file is big, so it take me around 15 mins to restart. That is time consuming. So I am wondering that any other solution??

Likely a conflict between add-ins which is only being triggered after launching pyRevit or one of the graphs therein. Check your Revit journal for API_ERROR issues which are not present when Revit is launched with no add-ins, and clean up any notifications in Dynamo around DLL conflicts.
