20191,vbox unhardened windows build - vm doesn't start,igntec,,"Hello, there.

I have built and installed Qt 5.6.3, OpenSSL 1.1.1, and Curl 7.75.0 from source

My LocalConfig.kmk:
VBOX_WITH_ADDITIONS=
VBOX_WITH_ADDITIONS_PACKING=
VBOX_WITH_VALIDATIONKIT=
VBOX_WITH_WEBSERVICES=
VBOX_WITHOUT_HARDENING=1
VBOX_SIGNING_MODE=test
VBOX_PATH_SIGN_TOOLS=E:\Programs\WDK71\bin\amd64
VBOX_INF2CAT=E:\Programs\WDK71\bin\selfsign\Inf2Cat.exe

My certificate is called mytestcert.cer

My build commands:
set BUILD_TARGET_ARCH=amd64
cscript configure.vbs --with-DDK=E:\Programs\WDK71 --with-MinGW-w64=E:\Programs\mingw64 --with-libSDL=E:\Programs\SDL-x64 --with-openssl=E:\Programs\OpenSSL-x64 --with-openssl32=E:\Programs\OpenSSL-x32 --with-libcurl=E:\Programs\Curl-x64 --with-libcurl32=E:\Programs\Curl-x32 --with-Qt5=E:\Programs\Qt5-x64 --with-python=E:\Programs\Python27
env.bat
kmk

My post-build commands:
comregister.cmd
loadall.cmd

Drivers are installed successfully.

VirtualBox.exe starts fine, however I can't start any virtual machine. The error is:

The virtual machine 'Windows 7' has terminated unexpectedly during startup with exit code -1073741515 (0xc0000135).

Result Code: E_FAIL (0x80004005)
Component: MachineWrap
Interface: IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}

Running VirtualBox.exe as Administrator doesn't help.

Build is unhardened, however it still should work. On Ubuntu unhardened build works fine. Do you know how to fix the problem? Thank you.
