Guest additions fail to start after upgrade

Host - Win10, Virtualbox 6.1.22 r144080
Whonix - Whonix XFCE 15.0.1.7.3

First start is ok, clipboard sharing, screen resizing, etc - everything works well.
But installing updates seem to break guest additions

Here is a dmesg from fully updated Whonix Gateway (the issue also affects workstation)

This is likely because of the kernel upgrade, for some reason guest additions are only built for the current kernel.

Issue and workaround described here just now:

Is Issue with failed to get display change request the same issue, a duplicate?
