If i have a usual browser session in progress, then open the menu on the top right of the browser and select “open guest window”, the browser instantly shuts down with no processes to be found in windows task manager. This is also what happens if i load up the main brave window which displays a list of my created profiles, and i select " guest mode".
Then, after that shutdown, if i start one of my normal profiles, i get the message that the browser didn’t shutdown properly and do i want to restore my session, and it will load up any open tabs from my normal working profile that i was using. I disabled the 2 extension i use, nocript and ublockorigin.
I did create a new test profile and checked to make sure it was a fresh clean profile with no extension etc. Trying to use guest mode or open a guest window produces the same instant closure.
version 1.40.109 ( upto date)
I have used brave for numerous years and for all that time guest mode has behaved the same, closes the browser down.
Do not be alarmed by the ‘Error’ and ‘Warning’ labels. With experience, using Event Viewer, one sees such alarms, often.
The object of the exercise – if you choose to take a look – is to be prepared and have that Event Viewer window open and in a location within your computer display, so that you can observe events that are being listed, while you are also using Brave Browser.
