Revit 2018.3.1 Hotfix installed and Dynamo issue

Hi, I had Revit 2018 and Dynamo 1.2 installed on my computer. Yesterday i updated to Revit 2018.3.1 hotfix , installation succesful. But now when i try to run dynamo it shows me a white screen,

I tried uninstalling all versions of Dynamo even the register, and then reinstalling Dynamo 1.3.2, but the same problem repeat.

Please help

I may suggest updating to Dynamo 1.3.3. this is what I run on R18.3.1 without incident.

It also looks like that Hotfix installs Dynamo 1.3.2. so there may be a conflict. May want to reinstall Revit after uninstalling all Dynamo, which should put 1.3.2 back on

I have installed Dynamo 1.3.3 , so the problem repeat
I will reinstall Revit but it will take me a long time

You could just try the Repair option for Revit and not full uninstalling.
