TextMeshPro 产生新字报错 NullReferenceException: Object reference not set to an instance of an object

您好！
请问使用 TextMeshPro 后在 IPhone 上产生新字体时报会错是什么问题？

建制环境：
Unity 2019.4
TextMeshPro 2.1.1

字体配置：
FONTSET.PNG


建制版本： Android (apk) 、IPhone (ipa)

运行环境：
安卓模拟器  Nox 7.0.1.0   ： 正常  (除了不能置灰等本身存在问题以外，功能运行正常)
IPhone 7 plus、 IPhone 8  ：  只要第一次遇到没使用过的字就会报空值错误，再次使用才恢复正常

重现方法：
开启包含文本框页面，文本框已于编辑器预先键入 "你好，世界！"

对文本框 SetText "你好，世界！真好！" ( 真 第一次被使用)
后台报错：NullReferenceException: Object reference not set to an instance of an object

文本框内文字被清空

再次对文本框 SetText "你好，世界！ 真好！"
正确显示 "你好，世界！ 真好！"
 
若有复数个文字第一次被产生，SetText 时会不断报错，得重复 SetText 直到所有文字被产生过才能正确显示

请问这是什么问题？

    更新：
    运行时报错没trace到行数，用 Mac 能看出错误的历程

    抱歉给谷主添麻烦了，最后发现是IOS建制工程的TextMeshPro有问题，全部 Reimport 后重新建置已经可以正常运行了，谢谢回复

    突然这问题跑到编辑器上了
    编辑器版本 社区版 2021.3.1
    不影响使用，但不知道怎么出现的
     (一直刷，重开就不见了)
