Can you perhaps try the current version as well? There's been one additional
change to iwlwifi firmwares since then:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=40e4162adfc91390f6fbbd8269f9439832af1dde
(I haven't tested either, I just downgraded to 20190502-1. Don't have the
mental budget to deal with another broken thing now.)
