my copy of Vivaldi seems to be terminally broken but everything i have tried to remove doesn’t work. after using the scudo purge it is still in my start menu and it stills boots up in a broken state
what do i do to remove completely and try a fresh install
I second this ^
Install Synaptic and remove it from there. I have used Vivaldi on KDE Neon in the past and I remove it using Synaptic, although you can also remove it from Discover.
