You need to make the difference between a crash and what seems to just
be an incorrect configuration which prevents your server to start. If
you look at the line above which I have taken from the pg_hba.conf you
have written in your last email, it is incorrect. "scram-sha256" is not
a correct HBA method. You need to use "scram-sha-256" instead.

I would advise to look at the documentation correctly first:
