I'm experiencing the same problem. As a host OS I'm running an up to date Ubuntu 22.04.1 LTS x86_64 with kernel 5.15.0-47-generic #51-Ubuntu SMP Thu Aug 11 07:51:15 UTC 2022 x86_64.
I'm using the latest VirtualBox from the Ubuntu 22.04 package repository: 6.1.34-dfsg-3~ubuntu1.22.04.1 The host OS is stable. In VirtualBox I'm running a number of guest Ubuntu 22.04 virtual machines. These all crash in some way or other every 30 seconds or so. Generally the guest's Gnome display manager crashes, the guest's desktop disappears and the guest's GUI applications terminate. I'm then returned to the guest's Gnome graphical login prompt, but at a lower resolution than normal. For me this started occurring on the 2nd September 2022.

Rebooting Ubuntu into the 5.15.0-46 version restored the avility to boot. The 47 version also corrupted the VM, so I had to use a backup. I don't know if the problem was really with new Intel microcode that was installed with the new kernel. VB kernel modules were updated by dkms with the new version 47 install, so that should not be the problem.
