This probably means the PostgreSQL user/process does not have access to
the file, either because it does not exist, lack of privileges, an AV
system blocking the access, or something like that.

I suggest you seach in the Windows Event Log, and various other logs you
might have there.

Given that, I wonder if this isn't the same issue being worked
on over here:

https://www.postgresql.org/message-id/flat/15858-9572469fd3b73263@postgresql.org
https://commitfest.postgresql.org/25/2189/

If you could help review/test that patch, it would make it more
likely to get fixed soon.

I think that's the same issue with stat() not working for files larger
than 2GB on Windows.
