ASWebAuthenticationSession won't open the Safari login window on Monterey

My macOS app uses ASWebAuthenticationSession for users to login to a third party service. It's worked fine until Monterey.

When I call start on ASWebAuthenticationSession it shows me the permission window as expected:

However when I click Continue nothing else happens. It does not show the Safari window and load the login page.

I've noticed these errors appear in the Console every time, so it seems it's having trouble opening Safari (even though I have Safari already open).

Any suggestions on how to fix this? Surely ASWebAuthenticationSession isn't broken for everyone?

  • The problem has been fixed just for Safari, all other browsers seem to exhibit the same old behaviour on latest Ventura 13.1 - like the queue of web authentication requests never gets advanced, and the only way to fix it is either close the browser auth window or restart browser altogether. And it happens on any major browser, except, Safari, of course. Please fix it ASAP

I’m still getting this issue on macOS 12.4. When I press ‘Continue’, this gets logged in Console:

20:41:59.415416+1000	error	kernel	<Missing Description>	Sandbox: com.apple.WebKit(30034) deny(1) mach-lookup com.apple.diagnosticd
20:42:00.553550+1000	error	kernel	<Missing Description>	35 duplicate reports for Sandbox: com.apple.WebKit(30034) deny(1) mach-lookup com.apple.diagnosticd
20:42:00.553559+1000	error	kernel	<Missing Description>	Sandbox: SafariLaunchAgen(66809) deny(1) system-fsctl _IO('h', 47)

The alert also doesn’t go away, even when I click ‘Continue’ or ‘Cancel’. I have to pkill UserNotificationCenter to get rid of it.
