Samba hasn't got to Windows 2016 yet, never mind  2019. You may be able
to fix your domain by demoting the Windows 2019 DC. If this doesn't
work, stop the Windows 2019 DC and forcibly remove it from the domain
with 'samba-tool domain demote
--remove-other-dead-server=<THE_2019_DC_SHORTHOSTNAME>

I fear that you may have terminally mangled your AD.
