I was having problems using GetAppCredentials (Githab), the way to solve this problem was to install the Uipath.Credentials.Activeites package and in the GetAppCredentials project to replace the elements that were giving error with the elements of the Uipath.Credentials.Activeites package. I hope I helped someone!
