Hi,

1.Please make sure that your server has already been install the latest update.

2.Some malware can also cause this problem. You can try to run anti-virus software to detect whether there is malware.

3.Run the following command:
tasklist /svc /fi "imagename eq svchost.exe"

That will tell you what services are being controlled by the service host. You can force stop the services to free up CPU

4.Here is a blog talking about the issue, check if it helps.

In addition, please allow me explain that from the support level of our forum, we can only provide you with as many solutions as possible. If you want to find the cause of the problem, it may need dump analysis, which is out of our forum support level, I would like to suggest open case to Microsoft.
