Little Error, while installing VM with LEMP on Almalinux

OS type and version AlmaLinux 9.1
Virtualmin version 2.021

I recently ran into a bit of a snag while trying to install VM with LEMP on Almalinux 9.1. Specifically, I encountered an error message that said: “Use of uninitialized value $backend in concatenation (.) or string at /usr/share/perl5/vendor_perl/Virtualmin/Config/Plugin/ line 90.”

I’m not exactly sure what this means or how to resolve it, and I was wondering if anyone in the community has experienced a similar issue or has any advice on how to fix it.
Looking at the code of this file:

enabled = true$backend

Not sure, if it has something to do here…

I would greatly appreciate any insights or suggestions that anyone may have.
Thank you in advance for your help!

Have all of you a wonderful Sunday,
