Error "Could not find the application. To refresh, make sure the application is open and the selector CV Scope is valid

I’m using CV Screen Scope. When I want to use CV Click like always, I click indicate on scope and I hit Screen refresh. When I do that, I’m getting an error “Could not find the application. To refresh, make sure the application is open and the selector CV Scope is valid”
Without this step, all the time I spent is waste. I can not copy paste the other things since I can validate them in any other CV Screen scope. How can I solve this error?

Possible Reasons:
Hopefully you are using activity inside CV Screen Scope. For all Computer vision it is mandatory to use CV Screen Scope and confirm it highlights application correctly.

Second thing is CV package version
Are you using stable version of CV ? If you are using alpha beta version then try with any stable version.

Thanks
