You did not mention if you rebuild VirtualBox and its kernel modules after
update of FreeBSD to 11.4-PRERELEASE.
If not, such behaviour is expected and first thing you need is rebuild
VirtualBox using sources of 11.4-PRERELEASE
installed in /usr/src.
If you already did that, you need to bisect revisions. Also, you may find
useful output of "svnlite help diff"
that documents a way to find differences betwheen revisions: cd
/usr/src/sys/some-subdir && svnlite diff -r NNNNNN:MMMMMM
