I am running Postgres 14 on a Windows Server 2022 Standard. While DB operations were running such as inserting, my server restarted, and, now the Postgres does not start. I looked at the config file and the last lines of that are as follows:

Also, as suggested by others I check Event Viewer and see:
2023-04-23 03:33:39.610 PDT [5804] FATAL: configuration file "C:/Program Files/PostgreSQL/14/data/postgresql.conf" contains errors
Since I am using psycopg to work with db, I am getting the following errors:
File "C:\Python310\lib\site-packages\psycopg2\__init__.py", line 122, in connect
conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) connection to server at "localhost" (::1), port 5432 failed: Connection refused (0x0000274D/10061)
Is the server running on that host and accepting TCP/IP connections?
connection to server at "localhost" (127.0.0.1), port 5432 failed: Connection refused (0x0000274D/10061)

For size limitation, I removed all comments:
listen_addresses = '*' # what IP address(es) to listen on;
port = 5432 # (change requires restart)
max_connections = 100 # (change requires restart)
shared_buffers = 4096MB # min 128kB
work_mem = 2000MB # min 64kB
maintenance_work_mem = 3000MB # min 1MB
dynamic_shared_memory_type = windows # the default is the first option
max_wal_size = 1GB
min_wal_size = 80MB
effective_cache_size = 4GB
log_destination = 'stderr'
logging_collector = on # Enable capturing of stderr and csvlog
log_timezone = 'America/Los_Angeles'
datestyle = 'iso, mdy'
timezone = 'America/Los_Angeles'
lc_messages = 'English_United States.1252' # locale for system error message
# strings
lc_monetary = 'English_United States.1252' # locale for monetary formatting
lc_numeric = 'English_United States.1252' # locale for number formatting
lc_time = 'English_United States.1252' # locale for time formatting
default_text_search_config = 'pg_catalog.english'
I have not a recent DB backup. How should I conquer the problem?
