actually facing same issue but on windows 10 21H2

[estimated1337]

i think its one of latest windows updates broke airhv driver but i cant find actual reason by myself

[Air14]

Run DbgView as administrator enable "Capture Kernel" try to start airhv then paste its output here

[estimated1337]

interesting that before some windows update it was working and i have intel cpu

[estimated1337]

can it be cuz of Hyper-V possibly enabled?

[Air14]

Yes, nested virtualization is disabled by default in hyper-v

[estimated1337]

i have disabled Hyper-V and some other related thing in windows components but it doesnt take any effect and also tried commenting vmx support check in airhv and got reasonable bsod

[estimated1337]

uploaded minidump of bsod here https://easyupload.io/jkfk0b

[estimated1337]

as i discovered it bsods here

[estimated1337]

also issue may be in Virtualization-Based Security (VBS) windows feature and i dont know why its enabled on my windows in first place (probably some windows update enabled it) and i dont know how to disable it
tried following this guide but its still active on my system

[Air14]

You should disable VBS, because airhv will not work as long as it is enabled

thanks for information i will switch from windows home version to pro one and try to

Increasing the virtual machine memory to 4G can solve this problem
