Could not load type 'YesNoAuto' from assembly 'UiPath.Vision.Core

[gtobject]

Error is thrown when I try to open any .xaml file.
Not sure this is because of version of studio (2020.6.0) or the framework project packages has problem.

here is screen of error

UiPath studio 2020 has incorporated ReFramework so now it is one of the templates shown on the studio starting screen (It took me some google search to find out).
