I'm also seeing these crashes in Crashlytics. Only iOS 17 Beta users are affected. I was unable to reproduce this issue.

Hi, I had the same problem。 Then I repeated the question。 for the following reasons：

look this code：

0 [self.view bringSubviewToFront:self.educationView]; 1 [_educationView buildCustomView];

Line 0： self.educationView Is a lazy load， therein create the UI, and also call buildCustomView method, （There is customization UITextFiled involved in this method） Line 1： It's called again the buildCustomView method

A crash occurs when the UITextField is released through the stack discovery， So I commented Line 1 code out， Then the problem was solved。 You can check to see if such code exists
