Hmm. You can still connect if you use?:

/usr/pgsql-13/bin/pg_ctl -D /var/lib/pgsql/13/data/ -l logfile start

If so that would to me point to one of the options in the -o string. I 
would try dropping/changing them one at a time to see what happens. I 
would say start with the items in the  "-c synchronous_commit=off -c 
fsync=off -c full_page_writes=off" section.
