This is a GUESS.....

I have only toyed with qcow2 VMs under KVM, so I am not sure what as needs to be rebuilt on kernel update, but with VirtualBox, (installed from Oracle rpm, manually build drivers), the kernel-devel, kernel-source and kernel-syms are needed.

However, there is a problem in 15.2 with the purge-kernels process that on kernel update will update the kernel, but not update the -devel, -source or -syms packages leaving the system incapable of building whatever kernel modules need to be built from source.

Like I said, this is a guess, but if there is part of your setup that requires dkms module builds -- this is one place to check.

No, I don't use any out-of-tree modules on the host. I only have Wireguard on one of the VMs - and that's working perfectly. VirtualBox certainly is a pain, which is why I moved to libvirt and haven't looked back pretty much the moment I first heard about it, which was when I had problems with the darn thing breaking with Qt fractional scaling enabled. As I've mentioned, it's really weird and at least *partly* seems like some obscure bug exposed by my... perhaps somewhat unusual (read - cobbled together from what I could find) setup.
