向 xml 添加新视图时找不到符号错误

Question

我最近将我的工作室升级为北极狐。我正在尝试在我的 xml 中进行更改并添加 textView 但我收到此错误：

error: cannot find symbol
        binding.tvUserBio2.setText("LETS MAKE THIS HAPPEN");
               ^
  symbol:   variable tvUserBio2
  location: variable binding of type FragmentProfileBinding

我尝试清理构建、无效和缓存工作室，但仍然无法正常工作。有人可以帮忙吗？

这是我的 XML。我尝试在 XML 中的任何位置添加任何文本视图，我得到了同样的错误。
