Please help - vivaldi config somehow stayibg

I tried to send an email and Vivaldi does not respond anymore. I tried removing it, sudo apt purge, then apt autoremove, then reinstalling. No luck. It always tries to send that email when opened. How do i delete ALL CONFIG FILES or STOP IT FROM SENDING THE EMAIL ON STARTUP

Ive tried cutting off wifi.!

Fixed by removing that profile by using the short time before it crashes to open guest wibdow, quitting, and vivaldi opening in avcount chooser modd
