when click backspace, we call DeleteSurroundingTextInCodePoints, then the app with textField crash.
简单来说就是按删除按键的时候，调用了DeleteSurroundingTextInCodePoints ，然后，编辑框所在应用竟然崩了，报出了上述堆栈BUG。这么低级的错误不应该发生的。

Could you please clarify if you are able to reproduce it with soft keyboard or only with the dedicated keyboard attached?

Surely it can be reproduced. This is a bug in the source code, which can be reproduced no matter what the soft keyboard, but another condition is that the soft keyboard calls DeleteSurroundingTextInCodePoints(), regardless of whether there is text in the input box. When the compose framework receives the delete command, it will check the text in the input box. If it finds that the text in the input box does not match the length of the delete command to be deleted, an exception is thrown. Then, the APP crashed. Note that it is not the input method crashed.

Description
Version used: 1.2.0-rc05
When called on a view within a fragment added with a <fragment> tag in a layout, FragmentManager.findFragment(view) returns either the containing fragment's parent, or crashes as it can not find any parent fragment.
I've attached a sample project which crashes on startup due to the bug. Replacing the <fragment> tag with FragmentContainerView or a framelayout with a manual transaction avoids the crash
