Does Windows 11 Hyper-V support Intel 12th gen

I read about several people having problems running Hyper-V on Intel 12th gen CPUs. The problem is the hybrid architecture of Performance cores and Efficiency cores. After enabling Hyper-V the host system does not boot any more. The only workaround is disabling all E cores in BIOS, but most OEM devices do not have an option for this.
a) Does this problem also apply to Windows 11 (current release build)?
b) If yes are the plans to fix this in future versions of Windows 11 (maybe 22H2???)

    I currently own 12700K. 8 performance (hyperthreading) + 4 efficient.
    All 12 cores (20 logical) are visible in Win10 22H2. I tested vmware workstation and Hyper-V. Under Hyper-v i gave all 20 cores to VM, installed win10 inside... Not had any problems...

    How they solved this I don't know bit it work well.
