I found the problem with my storage credentials. Thank you for your help.

Thanks for your reply。 "This button is not for logging in with a username; please note that I haven't entered a username, and it might be associated automatically. I have implemented the code as follows, and clicking the button doesn't have any response." "When I've registered, refreshing the webpage automatically triggers its appearance." I have implemented this method, but when I click, it is ineffective.

What I'd like to ask is, for example, when I've registered a passkey on webauthn.io, a window automatically pops up when I refresh the webauthn page, saying "Log in to webauthn.io with a passkey from the App," with a username button below. I'd like to know which method is triggered when you click on it.

I added a print statement in there, but I noticed that clicking the button didn't trigger this method. Is there any special configuration required to execute this method?

Thank you for your reply. I have another question. When a web page auto-fills with "Use the xx passphrase to log in to webauthn.io," there's a button below it. Clicking on that button triggers which proxy method, and what would be the recommended way to handle this method?

Thanks for your advice, I will now try to get the crash log from Apple.

There was a data signature operation, but somehow it crashed here. I don't understand why my switch crashed

I don't know what that means. This crash is listed in the crash log.
