Both the windbg preview and newer windbg's in the windows 11 and windows 10 SDK fail to attach to windows 10 21h2 (19044) with the following error:

bcdedit /bootdebug {bootmgr} on
bcdedit /bootdebug on
bcdedit /debug on

Setting

bcdedit /bootdebug {bootmgr} on

With VMware as the hypervisor is somehow the issue. Setting the other two options but not bootmgr does not exhibit the issue
