app always crashes on IOS when inputting to a TextInput the word 'near' (lowercase)

[yinonby]

Description

app always crashes on IOS when inputting to a TextInput the word 'near', see attached Snack.

It will happen every time you type slow enough so that the autocomplete feature of IOS will mark some letters.

If you type really fast, before the autocomplete is able to mark anything - you will be able to 'get through' (not carsh).

To make it more bizzare - it crashes for any combination of lowercase/uppercase, as long as the last letter ('r') is lowercase.

If you do enter it with a capital 'R', even when the autocorrect changes it to lowercase 'r', it will 'get through' (not carsh).

But when you delete and input it again with lowercase 'r' - it will crash again.

Issue persists on newest 0.76.5 version

I can repro on the snack, but have been having a lot of trouble getting this to reproduce locally on a recent main branch build using RNTester playground (tried matching correction settings, simulator version, hw vs software keyboard, etc).

If you're able to share a callstack (like from attaching to debugger with XCode), that would be very helpful to root this down a bit.

Anyone else trying to repro would also be helpful. This seems like it should be very simple to, so not sure the environment difference.

I was able to reproduce this issue on Snack; however, I couldn't reproduce it locally. On Snack, the crash occurs simply by typing the letter 'r'.
