Hi @loginerror
Studio and UiAutomation package use the 2018.4.3 version.
But I think we have found where the issue comes from: when installing the new robot version, the installer asks for a language. At first, we let French here, even if afterwards we set the robot logs in English in the robot parameters when installed.
But then we tried to reinstall the robots, putting English language as preference in the installer this time, and the LoadString issue disappeared!
So I guess it comes from the Installer preferences, and we need to be careful when installing the robot, since we cannot revert the language preferences without desinstalling robot.
