@rav I see that someone had similar issue:
Seems that problem might be strictly related to Abbyy product. But something is going through my mind. You said that it was working before and problem occurred just now. Please maybe try to downgrade UiPath.UiAutomation.Activities dependency to one version back in Manage Packages. Let me know if this has changed anything.
