Have you tried a restart of your computer? It worked for me when I had the same problem.

i have Restarted many times.

i reinstalled my Revit and Dynamo too.

But no Change!

Check your Revit journal and Dynamo logs to see if any hints are there. Then try checking your Revit add-ins and Dynamo packages by removing them all.
