@apennismightier,
Just tested on my end using the same method and the profile seems to have stayed removed. Can you try removing the profile data manually from the User Data
directory?
You’ll find this in ~\Users\ [your user name] \AppData\Local\BraveSoftware\UserData
From there, if you have three profiles you use, your main browsing profile data will be in the Default
folder and you should have a Profile 2
and Profile 3
folder, containing browsing data for the others.
Delete the Profile 3
folder, go to the Profile manager
again, 3 dots icon --> Remove profile
– now try rebooting and see if the change sticks.
