重现步骤

     <t-stepper defaultValue="0" disable-input theme="filled" data-id="{{item.id}}" bind:change="numChange"/>

    numChange(e){
      console.log(e)
      const id = e.currentTarget.dataset.id
      console.log(id)
    }

页面加载被阻断，加载异常，控制台报错 TypeError: Cannot read property 'createInstance' of null at Function.w._advancedCreate (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at c.createComponent (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at _o (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at ho (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at ho (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1 at xo (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at wo (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at xo (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at wo (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1)(env: Windows,mp,1.06.2402040; lib: 3.5.3)

有的时候好使，一刷新就坏，大部分时候是不好使的，和回调也没有关系，去掉change事件问题依旧

页面中放一个最基本的步进器也会报错，不知道是哪里影像的？ ["./miniprogram_npm/tdesign-miniprogram/stepper/stepper.wxml:view:3:2"] {currentValue: 0, classPrefix: "t-stepper", prefix: "t", disableInput: false, disabled: false, …} VM21014:80 TypeError: Cannot read property '0' of undefined at e (wxml.js?t=wechat&s=1730185288000&v=87f0058c6c91fa2242c293137da1d497:1) at h (wxml.js?t=wechat&s=1730185288000&v=87f0058c6c91fa2242c293137da1d497:1) at M (wxml.js?t=wechat&s=1730185288000&v=87f0058c6c91fa2242c293137da1d497:1) at m0 (:48:9) at :76:1 at po (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at t.jo.create (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at Function.w.prepare (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at Function.w._advancedCreate (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1) at c.createComponent (WASubContext.js?t=wechat&s=1730185288000&v=3.5.3:1)
