The first thing that leaps at /me is the inappropriate escaping of the sigil in the regex. The next is that you ask would-be helpers to take at face value -- that is, without code to back up the claim -- that "(you) created a hash...." ... which, for the limited purpose of this WAG, I'll take for fact, since it's a plausible sample of a hash.

But the next big ugly is is that you haven't given us enough with which to confidently jump off a cliff.

... but here goes anyway (sure hope the water's deep down there) (code and output updated for clarity):

use strict;
use warnings;
use 5.018;

# 1108508

my $error = qr/00000056|0000052D|05601111/;

my %pwd_reset_errors = (
    '0000052D' => "new password does not meet complexity requirements"
+,
    '00000056' => "wrong old password",
    '05601111' => "Friends don't let friends use Doze",
    '123xx51y' => "Not a Windows error (or undocumented)",
);

while ( my ( $key, $value ) = each %pwd_reset_errors ) {
   if ( $key =~ m/^$error.*/ ) {                          # Don't esca
+pe the sigil here!
      say "matched \$key: $key in \$error: \r\n\t \$value: $value\n";
   } else {
      say "Didn't find a match for $key [ $value ]) in regex $error\n"
+;
   }
}

matched $key: 00000056 in $error:

matched $key: 0000052D in $error:

matched $key: 05601111 in $error:
         $value: Friends don't let friends use Doze

Note the use of qr in the declaration of the string you're trying to use (I think -- sorry, Xtal ball is gebroke!) as a regex... and, of course, the use of strict, warnings, etc.

...and that the irony in the messages IS intentional. :-)
