`WebKit void IPC::ArgumentCoder<WTF::String, void>::encode<IPC::Encoder>(IPC::Encoder&, WTF::String const&) + 1108`

After publishing the app built with Xcode 14.2, the above (WebKit) crash report started to appear.
I don't know how to reproduce the crash, and I haven't received any inquiries from users, so I'm having a hard time finding a way to solve the crash.

If you have a solution (or cause) for the crash, it would be greatly appreciated if you could give me some advice.

## Steps to reproduce
- I'm really sorry, but I don't know how to reproduce
     - The crash log is coming up with Crashlytics, but I can't reproduce it at hand
     - It is certain that it occurs only in apps built with Xcode14.2 (apps built with Xcode13.4.2 do not crash)

## Device and OS
- device
     - 93% iPhone
         - 66% iPhone SE (2nd generation)
- OS
     - 87% iOS 16
         - Occurs on iOS15.5 or later
- Frequency of occurrence
     - About 1% of all users
