After updating the UiPath studio have you checked the dependent packages of the project? ANy packages pending to update to the latest version. If yes, try to update and check once.
can you please check whether any of the below properties are enabled in the studio?
As per my understanding the automation is validated for the rules set in the analyzer.
I found the solution in my project; the error was caused by the “Check Activity,” which I replaced with the “Click Activity,” and it is now working properly.
