Advice Request MsMpEngCP lack of IO operations?

It pretty much doesn't do any IO operations at all, only takes 1.6 MB of memory and not doing any CPU activity as far as I could observe. Same when doing scans. Is it something expected?

It's just the WD sandbox so it won't really hog the system in any way..Seems expected

Had just thought it was part of scanning engine(thus why it's sandboxed) of the Windows Defender, seemed strange why it's completely still. It takes about 40 MB of RAM at first after system boot. And event viewer shows some mitigation alerts. Thought it's kind of bug.
