Unable to sudo following upgrade to Catalina from Mojave

So I upgraded to Catalina but getting an error when I'm trying to use sudo. There're several threads and discussions on this topic already. Below is the error message from terminal.

(base) ardey-macOS-1:~ ardey$ sudo su -
sudo: error in /etc/sudo.conf, line 2 while loading plugin "avecto_policy"
sudo: unable to load /usr/local/libexec/Avecto/Defendpoint/1.0/sudo/sudoers.so:

Any ideas on how to resolve this? Thanks in Advance!
