My robot was working perfectly untill yesterday. Today I opened UiPath and I noticed this red line in the project output box:
‘The invocation of the constructor on type ‘UiPath.CV.Activities.CVTypeInto’ that matches the specified binding constraints threw an exception.’ Line number ‘534’ and line position ‘43’. Row: 534, Column: 43
When I start the process I get this:
In the log file I can read that:
11:22:13.3926 => [ERROR] [UiPath.Studio.exe]  System.Xaml.XamlObjectWriterException: The invocation of the constructor on type ‘UiPath.CV.Activities.CVTypeInto’ that matches the specified binding constraints threw an exception. —> System.MissingMethodException: Method not found: ‘Void UiPath.Core.Activities.KeyboardActivity.set_ClickBeforeTyping(Boolean)’
So the problem is the Uipath.AI.computervision package; I uninstalled it, reinstalled, accepted license, but still the same error. I tried also to install older versions.
I made a clean reinstallation of UiPath to the newest version.
If I delete the package I can enter the process but i see that the Uipath computer vision activity boxes are missing.
.Net Framework is 4.8
I have no more ideas on how to proceed, I need computer vision activities
Thank you for your help.
