Windows 10: Windows Defender Running Error

I bought a computer a few weeks ago. It is running Windows 10 home in S mode. I just found the following error in the Event log. It is about a Windows Defender error. Can anyone tell me if anything wrong with my machine. Has my machine been affected by any virus/malware?

Thank you very much for your help.
