I can not launch Windows Sandbox after upgrade to 21H1, it shows a Windows Sandbox failed to start. (0xffffffff) error. I find someone also asked about this issue in the Microsoft Community, but it did not get solved. So is there a chance anyone knows how to resolve this issue?

This issue seems to be self-solving after installing WSL and Virtual Platform. stop custom DNS service.
