At first:
Welcome to the Brave community! 
To your Situation:
Look into this setting: brave://settings/manageProfile
You can type this in the URL section like a website, and you should land directly in the right setting place. There you may see the same Profilename as you used at the zombiearch machine on your side. You can try to rename the profile and restart brave.
Else, you can create a new default profile for your zombiekali machine with the following command:
brave-browser --profile-directory="Default"
After this you can close brave and restart it from the launch icon as normal.
Another thing to try when you don’t want to do the mentioned stuff is to delete the SingletonLock file in the config directory of brave, as already discussed here. This would be in the following directory:
~/.config/BraveSoftware/Brave-Browser/
There you can delete the SingletonLock file. After this, it should be possible to start brave without any problems.
Important Notice: I can’t say what the consequences of this mentioned
unlocking profilesteps are but keep in mind it could lead to data corruption and other unexpected behavior. The preventing to launch brave is a security check to not lose or get data corrupted.
