Process not running unattended – UIPI Error

Hi,

I have a problem running the processes in unattended mode. The robot logs into the machine and starts the application that is used in the process but any step that interacts with the application (String Input, Click Step,..) ends with error and the process fails:

2024-06-11 10:46:16.917 +02:00 [INF] Executing step [“StringInputStep”, “df37cda9-5f4f-4752-854f-6fa36d86b736”].
2024-06-11 10:46:16.937 +02:00 [ERR] System.Exception: Some simulated input commands were not sent successfully. The most common reason for this happening are the security features of Windows including User Interface Privacy Isolation (UIPI). Your application can only send commands to applications of the same or lower elevation. Similarly certain commands are restricted to Accessibility/UIAutomation applications. Refer to the project home page and the code samples for more information.

What is the cause and how can I fix it?
