It certainly sounds like a challenging bisect, yes. I've 'bisect
skip'ed and then 'git stash save' / 'git stash apply' a handful of
work-arounds to narrow down hard cases like this before. It's also
worth keeping in mind that you can insert steps manually into a bisect.
For something like this where v2019.01 works and HEAD doesn't, I'd do:
$ git bisect start
$ git bisect good v2019.01
$ git bisect bad v2019.10-rc3
$ git checkout v2019.04
and see what happens.
