MMC stopped working pop-up at Hyper-V Manager

Hi all.

My desktop is running with Windows 10 pro and I turned on hyper-v manager.

And then I installed Windows 7 Enterprise to the virtual machine.

It is okay to use VM but I got an error "Microsoft management console has stopped working" when I turn on/off VM that it make Hyper-V manager close instantly.

I checked the event viewer and I found clr.dll cause the error.

Is there anyone who have same issue? Please help to find  solution to fix it.

Thanks.
