I’m having the same issue, or very similar.
I’ve switched between StudioX license and regular Studio. I have a hunch it is related, as I’ve definitely got access to ApplicationCard, which can open a browser but you can’t save it to a variable.
I’ve also Uninstalled UiPath and reinstalled and its still not working. I’m using W10, but the same process was tried in a fresh install of Windows (this time Windows Server), and flipped between StudioX and Studio. And its the same issue. Arrghhhh!
Can anyone help?
