Error loading Dynamo in Revit 2020 [Chromium error]

Hi! Since this week I’m not able to open Dynamo in Revit 2020.2.
It opens a new window but it’s not shown top front.
This doesn’t happen in Revit 2018 Dynamo 2.0.4.

When debuging a different addin I’m working on I notice a message in my output console that pops up when opening Dynamo.

Chromium Browser Messages*
ERR_ABORTED

My guess it’s that an update from chrome messed up with dynamo (somehow).

What I’ve tried without success:

  • Update Revit
  • Update Dynamo
  • Reinstall dynamo
  • Uninstall chrome

None of these actions solved my problem.

Any ideas?

PS. I can confirm this happen to another user I know.

does your addin use cefSharp or another embedded chromium?
