Can you run the update again with
GIT_TRACE=1 git submodule update ....
and post the output?
I have the suspicion that e98317508c0 (submodule:
ensure core.worktree is set after update, 2018-06-18)
might be the offender.
Could you try reverting that commit and check as well?
git clone https://github.com/git/git && cd git
git revert e98317508c0
make install # installs to you home dir at ~/bin
and then try again, as well?
(though bisection may be more fruitful if this doesn't pan out)
