I have just upgraded from MacOS Monterey to the latest Sequoia, VirtualBox 7.1.8 (I tried also 7.1.4) panics the kernel when a Windows 7 VM is launched. The VM startup process reaches the point where you can hear Windows 7s' jingle, the jingle audio cracks and jitters a bit and then you get the host kernel panic and a full MacOS reboot happens. I tried to uninstall and re-install the same VBox version and previous versions, but I always get the kernel panic. VirtualBox is practically unusable.
here is the panic report:
