Errors When Loading Dynamo

Hi all,
I have 50 errors on starting dynamo and starting a new file. Attached is an img of one of the errors, though most of them seem to have similar texts, all though it seems dynamo is working ok.

Any ideas what is wrong?

You’ve got a conflicting package version, or Revit add-in. Disable ALL Revit add-ins and see if that clears them up. If so one of them will need to be updated.

If not disable all your Dynamo customizations and see if that clears it up. if so one of those will need to be updated.
