Because I can’t restart the postgresql service, it crashes when this is the setup….
User postgres is the superuser, by the way.

I set up the password hashing method to scram and now no one can login to the server and that's not a bug??
If we understand the problem correctly, no, it's not a bug: changing the password type setting after deployment requires some work to change pre-existing roles. It is not possible for the server to do it for you, the passwords being encrypted.
I think the short answer is to setup pg_hba.conf so you can get a superuser login without a password (peer or trust) and then alter the superuser password and create/alter any users you want with new password in scram format.
