Can't show file for stack frame : <DBGLLDBStackFrame: 0x10c767ca0>

Start by reproducing the first-initialization crash through creatBtnClick, then inspect the RiveView.swift stack frame and the lifecycle around reset, setStateMachine, play, and enableAutoBind. Done means the initial Create action no longer crashes, while changing state machines and subsequent controls remain stable.

当我第一次初始化的时候点击确定会报错并崩溃，但是当我切换了changeStateMachine过后再点击确定就不会崩溃
