Virtual Box Fails to Start

After a recent update, I can no longer start VirtualBox. I get the following error:

VM Name: Debian

VirtualBox can't operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_VMX_IN_VMX_ROOT_MODE).
Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
ConsoleWrap
Interface:
IConsole {6ac83d89-6ee7-4e33-8ae6-b257b2e81be8}

I have found that if I run as root modprobe -r kvm-intel the problem is fixed. Is this expected, and I should just manually add it to the list of modules to load, or is it a regression that should be reported?

This looks like a known issue:
After upgrading to kernel 6.12, VirtualBox fails to start
