OS: Windows 10 (up to date)
Browser: Opera for windows up to date
Clicking links from Outlook (32 bit) desktop or Slack or any other application results in a 10 second delay before web page is launched in already open browser.
When I change my default browser to Edge the pages open instantaneously.
When running Process Explorer I can see that a new instance of Opera.exe gets created right away and then there is a ~ 10 second delay, at which point the new tab opens, and the extra process disappears. It seems like it's stuck inside Opera for those 10 seconds.
