I cannot find any version of windows image to be able to run on Windows 10.0.19043.x (21H1) with "--isolation=process" This page says you should be able to run 20H2 (?) on 21H1. https://docs.microsoft.com/en-us/virtualization/windowscontainers/deploy-containers/version-compatibility?tabs=windows-server-2022%2Cwindows-10-21H1#windows-client-host-os-compatibility Am I missing something here?
