NS_ERROR_FAILURE (0x80004005) on Start of Win10 virtualbox 6.1.32 after update to OSX 13.x Ventura

[St:Baer]

Unfortuantelly my Win10 Virtual Machine does not start after updating to OSX 13 Ventura.

The virtual machine 'Win10' has terminated unexpectedly during startup with exit code 1 (0x1).
Result Code:
NS_ERROR_FAILURE (0x80004005)

Version details:
virtualbox 6.1.32
Host OSX Ventrua 13.2.1
Guest Win10 (64-bit)

It looks like the two *.vdi Files can not be accessed correctly.
They are located on an external SSD, which is mounted into the OSX System.

The following steps didn't bring any success:
* Check Acces to Removeable Volumes in Settings>Privacy & Security>Files and Folders
* Discard Saved State in the virtual machines context menu ist grayed out
* Uninstall virtualbox 6.1.32, reinstall virtualbox 6.1.32
* Uninstall virtualbox 6.1.32, install virtualbox 7.0.6 (Allowing Access)
* Removing the drives from the Virtual Media Manager, re-adding them again. (Hence virtualbox has actually access to the files. At least I could select them to be added)

Please give me further advice, since I've got important data in the *.vdi files.

On Ventura, you'll have to run 7.0, since Apple forced no kexts. I'd suggest a complete uninstall of the Virtualbox app (your VMs will remain). Then reboot and try installing Virtualbox 7.0 again. If there are any Security Apps (I hear tell Apple is a tad interested in security...) have them open to receive and act on any messages while Virtualbox is installing.

Thank you @scottgus1 for your support.

I just did again, what I've already done before:

Uninstalling virtualbox 6.1.32.
Reboot the Mac
Install virtualbox 7.0.6 (Accepting that virtualbox can run in the background)
Reboot the Mac
Start the virtualbox

And now it works!

Great! Glad you're up and running.
