Hi @Avi,
It looks like not all components are updated (or possibly somewhere a version number isn’t updated in the configuration). First thing is to check all of the installed components with this list: GVM 21.04 (stable, initial release 2021-04-16)
From the other thread it looks like you were able to update with the package manager in Kali and are using the Kali provided packages so this is the next place to try for help with this version: https://forums.kali.org/
