Did you experience some hardware failure, or do the previous logs show any
other problems?
Can you send the output of
pg_controldata.exe -D $PGDATA
where $PGDATA is the directory where the instance is stored.
The needed command line is likely to be:
"C:\Program Files\Postgresql\13\bin\pg_controldata.exe -D "C:\Program Files\Postgresql\13\data"
Also, there will be a line of the form:
Latest checkpoint's REDO WAL file: XXXXXXXXXXXXXXXXXXXXXXXX
Can you check if the reported files exists in your pg_wal directory (it's a
subdirectory of the $PGDATA directory), and if its size is 16MB?
If yes, please check that the permission on the files allows the user starting
the postgres service. You could also temporarily disable your antivirus to
check if it's blocking access.
