Unattended Robot Error

Hi guys, last Few days I ran into a problem,
I’m Running a 24-hour process on Remote Desktop with an unattended robot connected to my orchestrator.
I have a parallel background and UI activities process.
problem is, that sometimes when I’m logging into the remote machine I see that the robots icon is blackened, a job is running in orchestrator but doesn’t do any activities, both background, and UI, I don’t have any idea why is that so,
please help

Good day, are you able to debug the process that is running or see the logs on the orchestrator to see where it is stuck? Also, is the process by any chance a REFramework process?
