Good news, I think I might have found a fix.
I am running Cyberpanel 2.3.7 ALmalinux 8
I do not believe the fix was that easy.
Keep a zip backup of your /etc/csf the script will restore it for you.
The script install csf in Cyberpanel and makes a small fix which would have crashed the panel.
sh <(curl https://sajetekengineering.com/wp-content/uploads/cyberpanel/install_csf_cyberpanel.sh || wget -O - https://sajetekengineering.com/wp-content/uploads/cyberpanel/install_csf_cyberpanel.sh)
Enjoy CSF in the latest version of Cyberpanel.
N.B. Backup your csf before running CYberpanel Upgrade because it will be removed, then you will have to rerun the script to reinstall csf and restore your backups
