Perl module installed but not listed in WHM

[Timedoor Developer]

We're having an issue with password validation in email account. Based on error_log (/usr/local/cpanel/logs/error_log), we found error like this:

Can't locate Crypt/Cracklib.pm in @INC (you may need to install the Crypt::Cracklib module) (@INC contains: /usr/local/cpanel /usr/local/cpanel/3rdparty/perl/536/cpanel-lib/x86_64-linux /usr/local/cpanel/3rdparty/perl/536/cpanel-lib /usr/local/cpanel/3rdparty/perl/536/lib/x86_64-linux /usr/local/cpanel/3rdparty/perl/536/lib /opt/cpanel/perl5/536/site_lib/x86_64-linux /opt/cpanel/perl5/536/site_lib) at /usr/local/cpanel/Cpanel/PasswdStrength/Check.pm line 104.

That error appear on log file when we change the input password.

We tried to install the module via WHM Perl Module installer and cpan, but it said that the module are already on newest version.

Here is the output of perl -e 'print join("\n", @INC);'

/usr/local/lib64/perl5
/usr/local/share/perl5
/usr/lib64/perl5/vendor_perl
/usr/share/perl5/vendor_perl
/usr/lib64/perl5
/usr/share/perl5

We also attached image when submit button was clicked.
We tried to restart cpanel service and disabled cageFS, but still doesn't work

Hey there! Can you try running the following to ensure all the necessary cPanel tools are in place on the machine?

/scripts/check_cpanel_rpms --fix

Could you also let me know your operating system and what specific action leads to the error? I don't see that perl module present on an AlmaLinux 8 machine.
