DLO agent Crash

Hi
I have problem regarding dlo agent. I managed to install the dlo agent on the computer. But I found a problem after the dlo agent is installed. After the dlo is installed, dlo will run as it should. But a few hours later dlo agent crashes and will be closed, then the backup will not work. Is there any problem with my dlo agent?
This error occurs on some computers that I have installed dlo agent.

And sometimes when i run dlo agent manually i get an error message and dlo will be closed again.
