Vm's don't start

[buddihst443]

Hi guys,
I'm new to vbox and virtual machines and could use some help.
I have virtual box installed on my windows 10 pc but I am not able to start vm's.
Every time I try it gives an error window, witch I have attached to the post.
I also found the hardening log to witch the error refers to but I have no idea what it means or what to do with it (also attached it to the post).

I have windows 10 pro and already disabled Hyper-v but it still won't work.
Can you please help me out ?

Thanks in advance

And the (zipped) VBoxHardening.log file?

Looks like the hardening log is posted above the picture.

That's an unusual exit code and a short log. I'm going to initially blame this on overzealous 3rd-party security software on the host OS. Built-in Windows Defender does not interfere with Virtualbox, but 3rd-party AV et al can and does, a lot.

As a test, uninstall all 3rd-party security software, let Windows Defender be the AV, then try Virtualbox. If Virtualbox then works OK, ask yourself if you really need other AV. If you really feel you do, set exceptions to everything related to Virtualbox in the security software's Exceptions. Note that this may still be required even if your PC is controlled y corporate IT overlords. You may have to sell the idea of Virtualbox to your boss.

The error code is unusual but has happened before. E.g. viewtopic.php?f=6&t=94372.
