The "permission denied" error would suggest that if anything was
corrupted, it was file-system metadata. That shouldn't happen on NTFS,
though.

It's more likely that for some reason (as previously suggested: quite
possibly AV software) the WAL file creation hit disk, but the result of
the system call setting its permissions never did.

It's quite likely that if you get "properties" on the postgresql data
directory and use the security tab to grant "full control" to the
postgresql user account then apply that change recursively you may be
able to start PostgreSQL.
