Hi,

Error: The processor does not support XSAVE. This virtual machine cannot be powered on.

I am in a trouble. Everything was working fine for years, but then last week I installed the Docker for Desktop and I started getting the following error whenever I try to turn ON any of the VM Machine.

First I get the "side channel mitigation" issue, then "XSAVE" issue start upon disabling the side channel mitigation from the VM Machine Settings ---> .

Even though I uninstalled the Docker, but things are same.
