When I launch Vivaldi I see instances try to load but then all disappear
Hello. I am having a problem with the 64-bit version of Vivaldi. It started a couple of weeks ago so I started using the 32-bit version, now that one is having a different issue so I tried to go back to 64. I have it set to run as admin so once I clicked it I had to approve it while I'm watching processes in Process Lasso. I see many instances act like they are loading then all of sudden they all disappear. I've checked firewall, antivirus etc.
Here is a clip just 9 seconds from the time I start the app you can see all the instances just fold up and disappear in Process Lasso.
Thank you for your time and help. Amanda
