Background:
We are loading a web login page inside ASWebAuthenticationSession. For login page, username and password have autofill password options enabled.

On click of the username textfield when we tap the system "Passwords" suggestion in the QuickType bar above the keyboard causes the app to become completely unresponsive.
No crash occurs and nothing is logged to the console.
The only option to get back to the app is we must force-quit to recover.

This issue is observed only on OS 26.6.1 and 26.7.1 other variant of the OS-26.x seems to be working fine.
We have tested the gmail app having the ASWebAuthenticationSession for login scenario, the similar issue is observed in that too.

Does anyone else also have faced similar issue ?
Any help/pointers much appreciated.

Since you can reproduce the same hang in Gmail, this looks more like an iOS Password AutoFill / authentication-session issue than something specific to your app. I would file it in Feedback Assistant with a short screen recording, exact iOS build and device model, and the smallest repeatable sequence. If possible, capture a sysdiagnose while the app is still hung, before force-quitting, and attach it to the report.

A useful comparison is the same login page in Safari, then in ASWebAuthenticationSession with the Passwords suggestion dismissed, and finally with the suggestion selected. Note whether Cancel or switching apps restores the session. If you can test one affected and one unaffected iOS 26 build on the same device, include those results too. I would avoid claiming a code-side workaround until that comparison isolates a specific trigger.
