Possibly Hardening problem [SOLVED]

[tagtag]

Sorry, this was solved.
Uninstall Virtual BOX, reboot, reinstall as administrator mode is OK
===============================
I have had the following error codes (Sorry in Japanese, but I hope that you can understand)
It does not even start at all.

仮想マシン"ubuntu-14.04-LTS-2"のセッションを開けませんでした。

The virtual machine 'ubuntu-14.04-LTS-2' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\Users\tag\VirtualBox VMs\ubuntu-14.04-LTS-2\Logs\VBoxHardening.log'.

I am using virtual box 5.2.14 r123301 (Qt 5.6.2) on Windows 10 Home.
I am using Windows Defender, thus there should not be AntiVirus software problem.
This has happened after the recent windows update.
But, removing recent updates did not help me at all.
I am glad if you can help me.
