Hi!

It looks like file 000000010000057900000067 is corrupted. I looked into 
this file and it contains data like other WAL files.

How to fix this error so that Wal playback can continue?

Master server is in Postgres 12 in Debian 10.3

Hot standby in Postgres 12 in WSL Debian 11.5

Can Debian version 10.3/11.5 difference cause this exception?
