I think because of this error is the cause for “Cannot bring the target application in the foreground.”

I used UiPath for On-Premise
I have already check that the workflow didn’t setting to work for background and the robot is installed in Service Mode.
Replace UI-based activities (such as Click and Type Into) with activities that can work in the background, like Send Hotkey (if applicable), or directly using APIs or data extraction methods that do not rely on UI interactions. This avoids the need to bring the application to the foreground.
Try Adjusting Robot Settings in Orchestrator:
In Orchestrator, under the Robot settings, try enabling the Login to Console option if it’s set to false, or set it to false if it’s enabled, as this can sometimes affect the robot’s ability to interact with the screen.
